Careful what you say to a self made engineer from the trailer park . . .
music: Skorned Psychosis
Edit: I did actually end up manufacturing the carb cheater and am currently on order number 2,018 or so - seriously ...
Can be purchased here: carbcheater.myshopify.com/
to put a definitive end to all the "this or that wont work" comments - everything in one video that address all the arguments.
Am I promoting the idea of putting a mower carb on a vehicle? no - but dang what a fun science experiment!
Now the Carb Cheater has raised a lot of questions - if I did go through the effort to sell that tech as a kit, would there be any interest?
Would be a lot of work on my part.
You should totally make a kit or release the files, this could be a fun thing for others to do lol.
Tesla and all the inventors where in that position at some point!
Patent it!!!
Respect!
Thank you for the lack of 'skip ad' target practice.
A hooptie V8 getting the same mpg as my hybrid. And a Ford too. Respect.
Ford worked on a high mileage carb back during the "Pogue" carb days and got it to 250 mpg on a V-8
@@mikedonovan9573 all the OEMs have figured out how to make a high mpg engine, but greed and politics has kept it out of consumer hands. We don't need catalytic convertors and all the complexity. A clean burning, efficient engine lasts forever because if all the fuel is being utilized there is no carbon fouling.
@@hoost3056 lets hope someone gets into some form of government position that realizes this and takes down emissions stuff and catalytic converter requirements. then we can have high mile v8s. if that person happens to be u, u have my vote, guaranteed
@@hoost3056 this is true and I definitely support your thinking, the government had issues with clean burning engines because they burned hot enough to make NOx emmisions thus the colder burning, less gas efficient and dirtier cat required modern cars. I am willing to admit that I know nothing of the dangers of either as I am not an environmental expert and I personally don't care too much. (I'd love it if global warming made ohio like south Carolina and got rid of Cleveland and toledo in the process!) Just a fun fact I learned from a video on why hydrogen engines never took off, and why mid 90s hondas are so good om gas.
Your hybrid is doing it with at least 4x the horsepower though.
That carb cheater of yours is great. I'm not surprised at all that the thing ran on a mower carb because I've messed with them enough, but that cheater of yours really puts the whole thing together.
I'm really impressed with your understanding of electronics, software, and mechanics. Pretty uncommon to find someone who's as capable with a keyboard as they are with a screwdriver.
I really need to get my feet wet with the 3d printing and app stuff, would really open up some doors for me on my hobbies.
Do it. Just buy one. Dont over think it. Get one in your hands and start messing around
I Believe in you. That you can and Will , believe in you too; you willing.. an able ready freed will ling. Sorta typa Human thing
@@CoincidenceTheorist I will when the time is right. Life's a bit busy right now so I'm holding off on buying a 3d printer. When I finally have time to mess with a 3D printer, there will be newer/better offerings on the market.
I've got a spare one if you still haven't gotten one
@Steven Reese I got an Anycubic Kobra Plus in the new year. It has been a hassle free printer so far short of having to input custom printer parameters into the slicing software.
This is honestly mind-blowing. 😮 you need to start mass producing that tuner you made 🎉 congratulations on this project! Amazing work
The first thought I had (aero-engineer) was the small carb was running a higher velocity at the same mass flow of air/fuel for the power the engine is making. That could create turbulence itself due to boundary layer effects. Your 90 degree turns also would be effective for mixing the fuel and air. I think your theory is correct on atomization of the fuel. Apparently you found a sweet spot in all of this and created something amazingly good at efficient operation. Nice job!
A tunnel ram enhances the mixing of air and fuel..a mower carb and bends chokes the engine, starves it of air..if it didn't he wouldn't need to create a vacuum leak.
Exactly his thoughts from the last video
@@brettjasonheadinventor he is running a "vacuum leak" via a app on his phone and a IAC valve.
@@jimbagle.3939 Yes, which means the mower carb is doing nothing more than driving with a choke on.
@@brettjasonheadinventor no man, it is more like the opposite of choke.
It's not less air volume than the carb at wide open. It's more air volume.
The "vacuum leak" is to regulate the flow rate of the fuel jet.
I'm 74 yrs old and you just blew me away ! Had visions of the Pogue Carburettor and the Long Range Desert Group right off the bat. Not just well...but extremely well done sir ! The World needs more people like you !
Once I owned a Honda CRX around 1985 or six It got about 35 to 45 per gallon. Such a great car and pretty fast.
You the man brother I'm 58 I've been working on cars all my life and I'll tell you what I never thought of that but I seen Ian Russell build a 3-wheeler chopper with Honda 6 cylinder engine and he put a regular I think I'm Otis a little carburetor something like that on there and made his own intakes all intake tubes into one little car and man that thing was beautiful ran perfect so you know I can see the way you put it out there on your board and that thing you made it kind of makes all sense I mean wow but like that other guy said boys going to be after you or want you to take it off look at that guy who made an engine that ran on water he disappears and sold it all the plans so fat back and bacon grease buddy you the man piece
Well we also need people to be really rude to him too. That was a big factor.
@@WilliamNordeste I also had a CRX 87' and my dad moved the cam forward one tooth and it went from 48mpg to 52mpg and pulled so hard it would torque steer! Ahhh I should have never sold it.
if we didnt the invention secrecy act the pogue carburetor would have been reality and many other similar inventions
I say sell it as a product,
There’s a market for it, especially in nowadays fuel prices reaching a higher price every day. Why not? Make 30 units, sell them for a fair price that you and the customer walk away happy, maybe apply for a patent? I say why not? It’s an extra stream of revenue to secure a brighter future! You sir, are American ingenuity at its finest!
Of course it's crossed his mind. I commented on this in the previous upload.
A patent only gives you option to sue an infringer at your own expense. Unless backed by a major commercial company you will not be able to afford that. Process totally skewed against small individuals. Better to just be known as the main guy in the field, the original inventor (something YT nowadays allows you to do, as you are doing right now) and just be the first, the best and most well-known.
Big oil will never let it hit the streets...period
@@XenonJohnD This isn't even a new concept, nor new stuff, just a 3D printed adapter anyone can make... try to sue that and you'll be the morning news laugh of the day...
I'll buy one
LOVED YOUR LAWNMOWER CARB ON V8 VIDEO !!
I've done a similar fuel conversion on a nice vintage 86 Chevy 4x4 van that came with a factory installed camping interior. I did the 4x4 conversion & engine swap a few years ago, my wife & I used this rig to tow our RV & assess the backcountry. It's running a 383 stroker, auto trans & a gear vender.
I purposely kept the running gear on the van old school with no computer as I'm somewhat electrically challenged.
I conducted several years of research prior to delving into these projects & to avoid melting down the newly built stroker motor. With a 4-barrel carb this rolling breadbox gets 10 mpg on a good day with a tailwind.
I first converted it first to run on hydrogen but output was not sufficient.
Note; Prior to experimentation & avoid engine meltdown issues I installed Manifold Temp. & Air/Fuel ratio gauges.
I ultimately converted the van to run very well on a gasoline vapor unit I designed that includes a float valve setup installed in bottom of the unit.. I'm currently running a chinese knock-off of 54 Chevy single barrel carb on the van. Bet a lawnmower carb like yours would work equally well if it was used in conjunction with a vacuum advance like you built.
Most don't realize that Henry Ford patented a working gasoline/kerosene vapor unit back in the teens. I was fortunate to observe one of Ford's factory units work on a local truck & was provided with the plans.
Only issue is that gasoline vapor freezes same as propane, I believe the solution is to introduce more exhaust heat from the manifold but got stopped a couple years ago due to health issues.
My goal was to try & exceed 100 mpg running vapor & distribute plans for free to those interested.
This goal would not likely be well received by our taxation & energy moguls.🤣
*The vacuum tuning unit you built is very ingenious, wish you were closer to Idaho to consult & incorporate on my project.
I'm now 81 with health issues so unfortunately the van may end up with another like minded mad scientist.
I would welcome your input.
Chuck T.
Kuna, Idaho
Chuck if you are still sharing the plans, id love to have scans and be able to pass them around. Your ingenuity is amazing
Chuck it's a small world, I used to live in Kuna
Are you still with us Chuck??
@@tims7219 Apologies' for the late reply Tim.
My vapor setup works very well on my 383 stroker & produces excellent EGT & air/fuel ratio results on the gages. Only issue is the vapor freezes up under higher rpms.
I introduced some heat via copper tubing to the exhaust manifold but was not enough to resolve the freezing. Unfortunately age '82' & health has put a halt to completion so will be selling the 4x4 van. Hopefully find a new owner who will add enough additional manifold/exhaust heat to perfect the operation.
Chuck, if you don’t mind could you send me your current design and the information you have gathered? I’m very interested in your ideas. Also, could you provide some more information on the Ford patent? I’m curious to look into that as well. Thanks.
Love this! You know people have forgotten that for MANY years single barrel carbs ruled absolute. Granted they were designed for automotive use and not a lawnmower, but the point is, they were very capable carburetors. My '62 Chevy II had a single barrel Ball & Ball that would roast the tires without hesitation, the added velocity of the charge was key. Also to note, I had a 1976 Monte Carlo with a 350cid engine that originally came with the large 2 Barrel which I swapped out for a Quadrajet. My mileage jumped from around 21 to 27 because of the much smaller primary throttle bores (as long as I kept my foot out of the throttle. The move to larger carbs was needed for the demand for power which quite frankly sealed the fate of the efficient single barrels because the general public started demanding power over efficiency.
Qjets were fantastic carbs
I would love to see a dyno comparison between the the two carbs to get an idea of the mpg-horsepower ratio
Only so much power can be made with that fuel.
@@Jeff-qq4zotrue, but the two setups might not provide gas milage prepositional to their prospective horsepowers
(A 300hp car could get 15mpg while a 150hp car, with more efficient combustion, might make closer to 40mpg)
@@snipesy the real question with ice is thermal efficiency
It made 59hp on a chassis dyno in another video lol. 140ish ft.lb. of torque
And it got around 40mpg on the Power Tour
This is the kind of content I like, I'm always on the lookout for informative auto related material. Man, this project really goes the distance. More of the same gets my vote.
Too cool. I remember a guy in the 70s, during the gas crisis then, being able to get 28 mpg with a V8. It's rather disappointing that my current truck only gets 14 mpg. I know the manufacturers can do better. You did it in your garage! You are amazing. Thank you for the great video.
This guy is great but something tells me he's gonna windup on a milk carton if he keeps this up🤣
exactly what i was thinking
I wonder if the nervous shaking he experienced after seeing the gas mileage was the thought of the gas cops pounding on his door in the middle of the night! lol Just Saying 😵🤣
@@robertburleyson7444 I'm with you! I wouldn't be tell anybody about something like this its just asking for trouble. A one on one showing is a safer bet if you feel this info should get out there. No one will be trying to get you in trouble and you wouldn't be having the shakes of the what if's.
@tatersncorn if anything, this could be what keeps gas-powered cars alive and safe from the takeover of battery cars.
He hasn't posted in a while uh oh
I would be interested in seeing how much cleaner the engine is running, emissions,spark plug readings. Sure runs nice! Enjoy the channel!
Keep in mind that this was only highway driving in a straight line in Iowa. Traffic in Iowa I would imagine must be sparse and the state is mostly flat. Modern cars can already adjust for fuel trim and timing advance and an ungodly amount of catalytic converters.
@@eaglewarrior8707 And most newer cars are not getting 40 MPG and flat, sparse highway either. Especially larger engines. Heck, most smaller engines are not getting that.
@@eaglewarrior8707 this is not the point buddy. you should focus if this engine runs with 4 barrel what kind a mpg should can do in same situation.
@@eaglewarrior8707 the results are the same with other underpowered vehicles, they are tested in similar ways, unless asked otherwise. It is the poor and stupit game of the government manipulators of money and the stolen corrupt venerated fortress of god's they stole and have claimed to have overthrown god. they are shit.
@@yunusertas you can easily increase your MPGs with a 4 barrel as well. Take the same concept he has here, adjust it and apply it to the 4 barrel. I don’t see how or why it shouldn’t work. Maybe not 40 mpgs but you can definitely get better than out of the factory.

I was wondering what kind of compression and cam size that 302 has and what was the timing set at while running on one barrel
Final mpg test is around 55:00. Super interesting video 💯 might have to find an old car and do this myself 👍
Great stuff man, ingenuity at its finest! I would love to see more detail on how you designed and built that idle air bypass to keep the AFR's around 14:1 though, and the app design. I'm good with all the mechanical and ignition stuff, but that APP and your FMB (fucking magic board) you built are beyond me.
Same here! I'm slowly teaching myself some basic programming in order to put a fully digital dashboard in my Frankentruck, but it's slow going.
I loved the comment about "over carbing" your engine. I had a 1985 F250 with a 351M. I thought I was hot sh1t as a teenager and slapped a 750 holley on top thinking I was going to get awesome power. I never did get it tuned right. I even switched brands to an Edlebrock 750. The thing still always ran like crap. A guy I worked with, built and raced drag cars and stock cars and informed me my carb was way too much for the truck. he took a 600 edelbrock right out of the box, slapped it on and the thing ran like a raped ape. in a half hour my guy took everything I thought I knew and tossed it right out the window 😂
@My Pronoun is WTF yes each engine i can be wildly different. The reason the 351 Modified didn't do well with a big carb is because of the cam. It was designed for a lot of low rpm torque, which made it a poor candidate for a big cfm carb. Basically it wasn't capable of using all the air available with the 750 and all the drivablity went away. To note, I also had a 302, that ran great with a 750. But it wasn't stock like the 351m.
@My Pronoun is WTF that’s because a 440 is massive
That happens sometimes
"he took a 600 edelbrock right out of the box , slapped it on and the thing ran like a raped ape " 😭😭😭 I'm dying here my man , what a legendary saying I love it bawhahahaha brilliant 💪😜😂😭
I don't really care for the edelbrock carbs too much... They work good and all, but a proper sized and set up Holley will always make more power (just a better design).
This is awesome. I would love to see this same setup on a 4 cylinder carbureted engine. I bet the gas milage would be crazy.
Most 4 cyl cars engines are 2 lt and up. I would like to try a set of 4 carbs for a 1000 or1200 cc motorcycle on a 4 cyl car

First of all... I am not a mechanic or a tinkerer even close to anything to your level. I'm just a necessity fixer, cause I grew up poor and things need to run. However, what you're doing I wouldnt' call impossible becoming reality. What you're doing is the most, real to life, hot rodder thing ever... but in reverse. Unlike all the 70's and 80's EPA shit... you're accomplishing some of it while keeping the sound of the car, the fun of the car, and useability of the car at a maximum considering. You're true to spirit it seems. Good job my dude, great work
I just happened to stumble upon this series at the start. I don't even know how it popped up in my view list but you had me interested right from reading the title of your first posting. I have been an automotive tech for over 30 years and I am quite impressed with your level of knowledge for your age. You effortlessly are able to explain all the science and engineering behind this project. I remember a long time ago hanging out in the garage with my buddies and discussing conspiracy theories about big oil companies buying up patented fuel economy devices just to keep selling fossil fuels. I really think your onto something here. I can't wait to see what happens with the 4 barrel. Please keep us posted on that.
I’m very excited for the 4 barrel test - will it give insane mpg? Doubt it - but there’s no harm in afr optimizing a carb to get the best fuel economy that that sized carb can provide
You do realise all of this has been invented tried and tested before now , this dude is just showing how it's done from his own levels of ability , the oil tycoons have killed people like him over and over to silence them so they can sell more fossil fuels , one thing I do agree with you on though he has a great head on young shoulders
@@ThunderHead289 heres a challange i have for you. roadkill style trip across america with the lawnmower carb. some spare tools beer or soda(idk if you drink or not). and some custom merch. let others follow you real time making the trip.
@@ThunderHead289 Funny thing is De Ja Vu I was working on a snapper lawn mower with a Briggs and Stratton engine and thecarb bowl was gunned after putting it back together I noticed somewhere I didn’t screw the bolts on all the way where a plastic piece feeds fuel air to engine and I said wow this is really atomized no fuel injection can get gas to be vaporized to smoke 💨 and I said this is what someone needs to put on a car and try maybe a bigger version of the same carb but oh yes it explained that the guy that made the carb for a car to run 60 mpg is real it’s probably a light car though. And it’s not far fetched carbs we can work on fuel injection and every new element seems to make the car worse to work on for average folks so they buy a new car
@@jonnykielbasa I have a built 351W with a Holley Demon four barrel I’m going to get rid of the Demon and put a cute little two barrel in it. At today’s gas prices 4 mpg doesn’t work very well
Luke, question for ya.... so I've been thinking about the astonishing results of this carb on your 302, and the theory behind the operation... so what I thought about was, in order to make it even more efficient, could you take advantage of this significantly less dense air/fuel charge by bumping up the compression ratio to absurd numbers? Something like 11:1 or even higher? 12:1 with water/methanol injection? I'm super curious how you could extract every bit of power out of this (with all due respect, and there's a lot of that) ridiculous setup? Since the increased vacuum signal already creates a rich condition without your nifty air bleeder device, and the charge entering the combustion chamber is significantly less dense, I would imagine that it would also be less prone to pre-ignition. Just a thought, and would love for you or any other knowledgeable folks to chime in.
Also on that note, would a super mild cam made for something like a truck engine to make more torque down low help with the efficiency by increasing port velocity?
Truck cams move the power band to a lower RPM, often you'll lose efficiency due to pumping losses.
I don't remember what he's using but the stock cam torque peak is around 2400 RPM, his is somewhere around there.
Truck cams produce more torque and better vacuum at low RPM but they also have more of a load just spinning at that RPM, that's why the torque is there. His efficiency sweet spot would be at a lower RPM, might work out if he had overdrive.
How can you bump up the compression ratio while using less fuel? That would create knock. What he did was pull out timing so he did not have to lower his compression. Higher octane fuel also helps to prevent knock with less fuel.
@@MCMinerHQ Octane is raised with ethanol. I don't run any of my carbureted trucks on any ethanol at all.
100% Gasoline gets better mileage and creates less unneeded heat in the engine.
@@MCMinerHQ it works out in lean conditions under vacuum, you can push the timing further on less fuel.
Problem is as soon as you lean on the throttle it pre-ignites.
That's how I got 24 mpg out of mine, under cruise conditions my timing was like 60* BTDC, which wound up letting it run leaner.
@@Stroke-it-2Handed If gasoline octane was raised with ethanol, that would mean the energy content of 93 octane would be less than 87 octane. This is simply untrue you have some homework to do. Fuels are cracked in large towers to get different octane and one tanker truck delivers 100 octane to the station and another brings 85 octane then the pump dynamically mixes from the two tanks to give you what you want. Octane/injector booster and cleaner bottles use 110 octane jetfuel and some light oils to boost your octane. The only time octane is raised with ethanol is when you tune your car to run e85 etc. Also, in fuel injected engines that can detect ethanol content, those engines will run cooler with more ethanol because they will have to inject 10-25% more fuel to make the same power. Some more advanced carborated cars would see a similar effect but I am unsure.
I think it would definitely be worth your time to try commercializing the system. Try it out on your 1964, and your 390 V8 truck for more proof of concept. If you could get 25 MPG out of the truck... (I know it’s low geared)
It doesn't work, or he would be rich beyond belief.

@@hoost3056 The Pogue carburetor comes to mind...
He ain’t the first and neither was the guy that did the basically the same thing in the 70’s that turned up dead and all his information on how he did it was taken and kept under wrap.
Engineers did come up with better carburettors…it’s called fuel injection.
Well said and I totally agree with all your points
You do know the eventual has to happen. A complete intake manifold replacement with 8 of those carbs stacked up like a Ferrari with a stack of Webers! I DARE you!
I want to see 4 1-barrels!!!!!
Then it would be a Ferrari no !!!🤣😭😜😜😂
The general idea behind the spread bore (a.k.a Quadrajet) is to run on as small of a carb as possible until you need the extra air. Carbs work best when they have high flow
This is the coolest stupid thing I've seen that worked soooo much better than expected, as it wasn't expected to even work. Great work on working out all the problems.
Loved the comment about coming from the trailer park-where you've been in life is never as important as where you are going. In life, we regret the things we do a lot less than the things we didn't-if you're unsure about how to improve your life, action beats inaction every single time and you miss 100% of the shots you don't take in life.

Well done.
Luke is well on his way to RUclips legend status. 👍 dude I can't get enough of this project!
I am super interested in how you made that automatic air fuel tuner. I would really like to see how you set it up! Do you read o2 values, and use the vacuum port to let in air? how do you know what voltage is 14.5/1 ratio? (if that is how you did it) But This is so cool! I've been following this series having so much fun!
/\ Everyone comment and like this so that perhaps he makes a video about it.
He uses a wide band and feeds it into his custom air bleed computer
Wideband 02 , arduino and a stepper motor to open a vlave. I have a 3D printer and build things on CAD . I get what he's doing here. Id learn how to program Arduino before you even attempt to try this
As someone who is very familiar with carb tuning and carb function, the outside-the-box thinking to allow the carb to run rich and create a controlled vacuum leak behind the carb (motor side) to lean the mixture is brilliant! And using the large GM idle air control valve, running from an open-source Arduino reading air-fuel values via O2, man, this is just my cup of tea! Nice job and so glad you shared!
Same here, I'd be interested in the plans and or a kit to do this ourselves. I see a lot of comments about oh it's just Arduino and anybody can do it, but that's total nonsense.
I would be very interested in seeing a full pull with the lawnmower carb setup. Daily driver looks to work fantastic and mind you, I'm not looking for quarter mile figures, just curious as to how a full pull would be.
I don't understand why you would think that this wouldn't work. When I was a boy, the neighboring farm had an old international dump truck with a 600 cubic inch inline 6 in it. The intake manifold and exhaust manifold were mated together, and it had a tiny 1 barrel carb on it.
It was decent on gas, but it had to completely warm up.
Easy to say now.
That was an easily earned subscription. Good job. You could nearly single handedly save the entire classic car industry.
Turning down the pressure made this carb WORK. I'd of considered doubling the fuel bowl and missed that. An amazing level of information,
As a 3D printing enthusiast (custom built my own 3D printer out of the parts of another), I would highly recommend you use a 0.5 (what I run) or a 0.6mm nozzle, with layer heights around half the nozzle size. High resolution for that type of part probably isn't super necessary to its function. Also, your part probably doesn't need to be as beefy as you made it, considering it's not running under any real pressures. Instead of making the base of it so thick, maybe add ribs instead. Slim it down, take a lot of the unnecessary material out, and save yourself some filament money! Great work man, your MPG result is pretty crazy.
I'd recommend layerHeights =< (nozzleDiameter/phi) for strength. I'd say go equal to that number for speed & strength.
I like lineWidth = nozzleDiameter too.
I agree, 0.6mm diameter is a great nozzle in terms of speed and detail.
There's also an interesting recent video by CNC Kitchen that I'd seen which details the maximization of printing speed with respects to volumetric extrusion.. The title is "Easy Hotend Benchmark for FAST PRINTING Profiles"
IMO that idea is revolutionary in the same sense of applying the small engine carb to the V8.
If you set that up then you will save so much of your valuable time! ..especially if you want to mass produce kits.
@@Paint0nBrush when he closes the throttle the vacuum probably jumps up to around 29 or higher which puts atmospheric pressure on the outside trying to collapse the plastic intake, I say beefier the better especially under the hood with the heat.
I would definitely like to see this run on a slightly more definitive fuel measurement, put a gallon in a container and tie it in then drive it till it’s almost drained measure the remaining amount in the container and calculate mpg
Agreed... There is too much variance in how a gas pump nozzle measures a full fill-up to rely on that...
@@CurmudgeonExtraordinaire except the regulation and regulating body and regulators and inspections but okay
@@colormesarge -- All the regulations and inspections do is try to ensure that a pump measures a fixed amount of fuel within an acceptable variance, not that it is consistent in when the nozzle thinks the tank is full... They want to ensure that if the pump is charging you for 5 gallons of fuel, you are actually *getting* 5 gallons of fuel.
Nozzle shutoff is what can vary and makes his way of testing potentially inaccurate... A pump speed (gallons per minute delivered) can vary over time. If it is pumping at a slower rate, it will allow more fuel to get into the tank before the nozzle shutoff occurs... I've been able to get over a gallon of extra fuel in a car by pumping slow... I've also seen pumps that delivered fuel so fast that the nozzle would kick off when the tank was only half full...
The fuel climbs up the filler neck and shuts off the fuel. That's got to be accuracy within like 2 oz.
Especially when it spills out on the second fill.
@@CurmudgeonExtraordinaireWhy would it not be that accurate?
Watching this is cross between Mr. Wizard, Evil Mad Scientist and a curious mind. That could be very FUN and dangerous. Take me to the merch!
doing a awesome job on this, way back during bush and gas hitting 4.00 a gal i was fooling with hydrogen generators to increase gas mileage. managed to get a merc capri from 25mpg to 45 mpg. i would love to see you add a hydrogen generator to your lawn mower carb which would be pretty easy to do. i bet with the combo you would hit over 100mpg
Do you have any videos or info you could share about your hydrogen setup? These gas prices are giving me PTSD every time I fill up my truck.
Now comes the time to start selling the adapter
This is really cool I hope you sell kits with parts to make it run on 265, 283, 301,327 abc/ 260 289 302 sbf/ 273 318 s mopar. I’m on FB pm me with cost for each setup I love it I’ve got plenty of fast hot rods but would way rather drive an old car with your genius kit than a Toyota everyday
I remember watching the video a year or so ago when you first put the lawnmower carb on the maverick, glad to see you followed up with the project and are selling units. Keep it as down low as possible, you know the oil companies and some other powers won't like it and will probably end up trying to buy you out or force you to quit making it. Do you have a patent on your product yet? Need to do that, but that will make more entities aware of it/you. Please keep me updated as your journey unfolds
Carb cheater and the lawn mower carb are completely desperate things.
The lawn mower carb was the most regrettable thing I ever made.
Please can you give us more on the remote idle air control feel like this would help on more carbs
Not a fan of the phone app, I’d rather have 3 buttons on the dash “idle” “town drive” and “LETS GOOOOOO” mode
Tell us more about your electronic idle air controller.
I bet that thing actually got 80 mpg. I'd like to see what that could do in a smaller, lighter, more aerodynamic car like a Prius with the battery removed for weight savings. You're a genius. You certainly know what youre doing. Keep fooling with this.
Hope the oil companies don't scrag you like they did that young man with the S10 and the guy with the water car.
u talking about the s10 with a rotory engine?
This is mind blowing. Obviously you have got a lot of mechanical and electro digital and drafting/engineering knowledge. Got to say I am extremely impressed. Very well done. Keep up the experiments and best wishes in the future.
Amazing. I wonder how well that would work on a 350 SBC with a TBI. I love my 90 Suburban but it's too expensive to drive. This would be an amazing revolution.
I'm brand new to carbureted or tbi stuff, what is the difference between carbs and tbi carbs? I know there are electronics involved... also, can you run an old school carb (or mower one) on a tbi car with obd1 or obd2?
A tbi “carb” (it’s really just a old style fuel injectons) is a fuel pump going to a mechanical regulator that then feeds the fuel through the two big injectors on top of the throttle body
I would treat that 41 mpg with a bit of skepticism and here's why. Your distance traveled was only 39 miles which is way too short to establish a reliable mpg number and secondly filling the tank at a service station gas pump won't reliably top off the tank with exactly the same volume of fuel each time. That can easily vary depending on the horizontal position of the car fore and aft and side to side at the time of fueling. I can see how that volume could vary by a pint, a quart or even a half gallon. With only a 39 mile drive that fuel volume difference can skew the mpg number quite a bit. Your theory of better gas vaporization sounds very plausible and increased mpg with that small carb to me is believable. What I would like to see if for you to do the same test and burn a much larger volume of gas over a greater distance. Enjoyed your video very much. Very educational stuff!
Your absolutely right about everything, I see a half gallon variable depending on the slight angle differences between stations. Every car is different too, mine gets less fuel with the front down hill.
I will say in defence of the MPG number he got that his car with a 4 barrel carb might get 15mpg on a good day, so the setup he got is still a significant improvement even with that variable at the pump.
Agreed, I would love to see a measurement after a whole tank.
That is amazing man. I literally had to see it to believe it. What an achievment.
If a backyard tech can get a v8 on 40mpg on a 40 year old POS car, tuned by guesswork, then we should be getting 400mpg by now from legit OEMs - but this PROVES we are being lied to.
Nobody is being lied to... Man this comment section of packed full of idiots.
Would love to see this on a Lima 2.3 4 cylinder in a ranger or something. Maybe a 240/300 or smaller falcon straight six.
So many cold, early mornings fighting my 2.3, cruel words, starting fluid and violence emanating from my driveway for the world to hear just for the pleasure of using a motor that could barely pull a booger. Ahh the nostalgia!
What size lawn mower did the carb come off of cant believe i forgot to ask
Also look into a briggs carb for the 18 hp twin cylinder engine those carbs actually sit on a vertical manifold and may actually work even better for you
Take my money! where can I place an order!!!😁😁😁👍👍👍
Hey, I know this guy!! No better man with a torch around👍😉
TIG up and adapter!
Enjoy your videos!
This is one if not the best video I've ever watched on utube. Great content.
I'm incredibly impressed by all of this. 1st, your 3D printers are awesome, I print a lot of Priline CF PETG and it can be a pain although I use much bigger tips. 2nd, you took Adruino to another level and that controller you built has a ton of potential I believe.
Hi Luke, I just have to thank you for the incredibly informative and helpful content you put out. Very impressive, you've helped countless numbers for sure. Please consider creating some type of Carb Cheater tech kit. You would again be helping countless numbers in a world where rising costs are pushing many to make some tough choices and find efficiencies wherever possible.
With some of the highest food prices and gas here in Eastern Canada nearing $9.00 a gallon it's becoming quite a struggle for many, myself included. I would quite happily rip into my daily/work truck, an 88 F150 with an aod trans, remove the efi system and convert to a similar setup you've accomplished with the Maverick. The knowledge and understanding to put that setup together has proven to be quite valuable given the interest shown. I stand with them and would definitely invest in what you've created. Cheers from Canada
Definitely a cool video, I have to wonder what dyno numbers would show and how it would do on high RPM WOT pulls. My guess is an engine that makes 300hp peak would be around 80-90 with this setup, but you have to remember it doesn’t take anywhere near 300hp to get down the road. In a 2500 pound car to cruise 70mph on level ground you’d probably need like 25-35hp, pulling a steep hill at 70 is going to need something closer to 100 but I would basically assume the driving experience would be akin to driving an old VW beetle vs a modern one. Cruising on flat ground at constant speed there’s just no difference in power demand and in city driving you have so much advantage due to gearing only running in 1st-3rd that low peak hp numbers don’t make a difference.
it makes like 50hp
Don't know why he is so surprised gm,ford,chysler all made one-barrel carbs that were basically a lawn mower carb and if you dialed those back you can get similar results and to be honest you can do it with a regular carb by restricting the fuel with lower fuel pressure and leaner jets.
Lol comparing a 1 barrel to a lawn mower carb. Like 1/3rd the size dude. And no one at all beleived this would work till it was literally documented in this video series.
Dude! I've wanted to experiment with something like this for over a decade. Glad a fellow Iowan was the one to try it out. I've been looking at various carbed cars the past couple years, intent on getting back to my roots, and now I really want to try that setup on whichever I end up getting. I'm hoping for the 78 Buick Regal V8 if all goes well the next few weeks. I'm moving from Texas back to Cedar Falls soon, too, so I'd love to have someone as motor-nerd as I am to bounce ideas off of. Rock on man! 40mpg in a 78 Regal for daily driving and road-tripping is my main goal for the year.
I am impressed! Not enough techs in the industry with your caliber of understanding and ability to think out of the box!
That was ridiculously impressive! I’m blown away on multiple levels on what you’ve accomplished here. Wow! Is all I can think of. You’re intelligence and understanding of fluid dynamics is amazing. Would love to be friends and pick each others brains and share knowledge. Bravo! Compliments!!
Here I thought the music was Alice in Chains. I have a new band to listen to now, thanks for giving credit, I'm shocked Skorned isn't more popular.
I love this video. Great job explaining the theory. I think your "controlled" vacuum leak is brilliant. Do you read data from your AFR gauge for the feedback to the controller? I think a video detailing the controller theory and design would be very interesting. I would buy a kit from you if you made one, really! Well done!
Really enjoyed this video.
A lawnmower carb on a 302 is a hilarious idea, but the way you’ve done it and the results you’ve achieved are really impressive
I was like most everyone else on the size of carbs needed, then I got my '73 Ford F-250 with an FE 360. It came with a 2 barrel, and I immediately thought like most everyone else that it'll need a 4 barrel. Then I found the math and found "360 ci x 4800 rpm divided by 3456 = 500 cfm". Question appeared then, how often will it be turning 4800 RPM? (hardly ever), it makes maximum horsepower @4000 RPM and maximum torque @ 2400 RPM. So a Holley 500 CFM 2 Barrel carb is more than I'd ever need. But increasing it's fuel mileage with that setup is definitely of interest to me, especially at these prices. Let's keep this going.
So at 70 mph and 2500 rpm he only needed 218.5 cfm to run the car.
@@mikedonovan9573 That's at wide open throttle. Way less airflow needed to just maintain 70 mph.
In theory, a vacuum seconday 500 cfm 4 barrel would be better. The primary side would be smaller, giving a much better signal and mix. This is why Quadrajets were popular. Very tiny primary and gigantic secondaries. Thermoquads as well, even if they do leak.
You should try a Harley CV40 carb. It would probably be a better driver. The Buell Blast also uses a CV40 for a 500cc single cylinder with an automatic choke
Do a distance run; Instead of ~37 miles, try ~370 miles! With that short of a run, there are too many variables, like the angle of the car, or the temperature of the fuel in a full tank of gas, that can really skew the results with that small of a percentage of the total volume of fuel used in that run.
Try that Holley 390 CFM carburetor, with the same mixture control module and same ignition timing curve. I'll bet it will be close, but not quite as good as the lawnmower carburetor, just because the venturi velocity won't be as high, and the fuel won't atomize as well.
I like your era of music my brotha👍 I'm a huge Primus fan myself. Keep on doing what your doing and thank you very much for the awesome content my brother.
Man, such an excellent video! Thanks for releasing it! This gives me some interesting ideas for something like a 3 barrel carb with a very small primary and barrel for light load and two much larger secondary jets and barrels for power. Good ideas bring on more good ideas! Keep up the good work! Subbed.
I wouldn't be surprised if tomorrow ur on the news as a suicide.....not tryna be negative but look at all the other people who have done something like this they disappear or are found dead....car runs on water guy ? Be careful man
Your grasp of the tech involved in what makes an engine run is very impressive. very well done young man. Yep I may just try this myself, I have an inline 6 with a two barrel on it and a pile of lawn mower carbs.
I pray you can get this mass produced as I would love this 😀. Prosperity to you and your family. Please make us a update
l keep rewatching these videos, there really well done... l cant wait to try the same thing...
I love how you think my friend.
I realize this is an older video. However it's new too me.
To Your question on should you publish your findings?
My answer have multiple cars or examples for science & safety.
Keep that big brain of yours healthy!
I love this experiment.
Cheers

Oh my! I just noticed that Luke is using the wiper/washer reservoir as a recovery tank for the radiator.....😊
The maverick I try to do everything as low budget and trailer park dystopian as possible
@@ThunderHead289 take a peek.....ruclips.net/video/XHZXAz9WP9M/видео.html
So happy you continued this series Luke! Always a pleasure to see what you're up to. Happy you show the nay sayers wrong. Have a good weekend!
Would be interesting to see emissions and EGT readings. Congrats bro, you're a petrol head with the brain of a genius.
Okay next challenge, four weed eater carbs in parallel
I think you did well...in 1982 I worked for Honda we had ordered a few Civics that had a little tiny one inch or less Throttle plate on them and they were apparently good for 62 miles per gallon ..fun fact .. That air in a smaller intake will travel faster than air in a bigger one..plus if you want to increase air in a smaller pipe just mount a small egg into the intake with a variable height slider ..it will pull in more air..old german Tech
What do you mean increase air in a smaller pipe?
@@yeboscrebo4451Air velocity will increase but volume will decrease with an egg.
Carb conversions are my favorite. Me carburated my previously EFI Honda Civic for funsies. First version was a VW beetle carb. Second Version was the WEBER 32/36. I used a 1990 DPFI intake manifold and made adapter plates. I think my next project will be my vg30 on my Nissan hardbody.
It is always nice to see someone who shares the same hobby.
Am l way off in thinking you've converted a simple carb intake into a mostly mechanical throttle body injection system? It seems that your a/f ratio voodoo mixer takes that carb from static to reactively dynamic. I hope you're going to dyno this set-up and share the results...
That would be nice...dyno comparison of regular carb to the mower setup..and what are the differences in power/torque..
@@renwickconolly2839 that and the vehicle weight and drag coefficient would tell us horsepower required to push that Maverick around. Thinking about fabricating a restricter plate for my fuel injected car to boost mpg...
It seems that modifying an electronically injected car that already has sensors might be even easier. Less metered air = less fuel for greater mpg.
It would possibly pick up HP on the Dyno at high rpm the velocity speed over the carb jet would pull a good amount of fuel so create a air leak metered with fuel you would be able to easily tune it and create as much cfm as you need
On a lil lada or small engine car it would probably be unbelievable. Theres lots of drivers out there that accelerate slowly and would totally buy these if u can dial it in to work with some inline 4 or 6s.
I would love to see what this would do on a cheap little geo engine, this type of efficiency on an already efficient setup would make for a cool hypermiler.
Wow, just wow there isn't much else to say. Your project was outstanding. It would be interesting to do a dyno comparison of HP with the 4bl Holley and the Lawmower carb. However regardless of any power loss I would be very interested in having something like this in my next vehicle build. Is this something that you would consider doing again or for me? Thanks for any and all thoughts, opinions, advice, or answers.
Very cool work done there.
I would've predicted you would be the front car in a long traffic jam all the time ;o)
Now how about printing an adapter to mount 3 or 4 of these carbs and have them progressively start delivering air/fuel when throttle/engine power demand becomes higher.
So all the time been able to drive on just 1 carb, unless more power is desired.
That is a great idea I think!
You're obviously a very smart guy and extremely competent at many things. Im curious though, why you would play copywrited music on your video and remove the monitization of this amazing video....
the next step would be a longer road trip with E85 gas
I really enjoy your work not only on this project, but on most all your videos. When I have questions about the carb or timing on my Mustang your videos are my go to tech manuals. Thank you for the content and all the hard work that goes into making it.
Dont publicize, keep sharing
Do I see a new industry starting here? Kits complete with adapters for all the popular engines? Custom builds by various shops?
He can not modify anyone else's car or possibly sell kits. EPA fines for changes to the MFG's design due to emissions is 10K and possible prison time for each infraction. Found this out during the HHO craze back in the 80's
My dad bought a new impala in the early 70s in orange county California. He said that it had a big box over the carb. New shit, he assumed. Thw gas gage didnt move, for over a week. About the time that he noticed this car was getting better than 50 mpg, 3 men in black showed up, with another imapala, demanding to trade.
Ok here is my idea for the next step of this project. Print a new manifold adapter that holds 2 or even 3 lawn mower carbs. It would maybe look like a little blower hat. The carbs could be linked together/ isolated depending on performance needs. You could even figure out a way to stage them to act like secondaries if you wanted.
Yes. Volume/horsepower on demand is where the interest would be. Certainly impressive that he pulled down 40mpg in a big, heavy, V8 car, but it's not a hot rod. People interested in mileage alone could just buy a 4 cylinder, small car.
But those of us who want high horsepower old V8's that can cruise with reasonable mileage would be very interested in this.
What would be the point of that honestly , the whole point of this project was to see would it work peroid ..everything else was a bonus ...by adding more carbs ..your just going back to a fossil fuel guzzling engine , as homer said alot .... Doh !!!😭😂😜🤣
@@borisjankovici662 got a sad thing to tell ya my man ...soon and I mean real soon you won't be able to drive them on the roads no more the way things are going , eventually there plan is to close the petrol diesel fuels down completely and make everyone drive electric or hydrogen powered engines unfortunately, I'm actually with you on this not against you but take a look at what Europe's promise to the green house gasses crap that's going on right now...USA is next all over bullshit climate change a natural phenomena, there trying to blame on all of us ..what people forget is what volcanic eruptions but also the ones that just smoke continuously all over the world let of daily is far more pollutants into the atmosphere that we let of in 20 years world wide ...but we're still all to blame , same with sea weed , and animals and all the other stuff that naturally occurs in the planet we live on but there is no mention of any of it , the only bullshit we hear daily is stop driving gas guzzlers were going to kill the earth , stop industry , they just want to fleece us all in taxes as they usual do that's the end of my rant...u can prob tell I'm sick to the bleeding teeth of it all and sick of paying taxes over a nob existent bullshit theory the crazy so called green tree hugging scientist keep coming out with , and that other spastic the ex vice president of the USA Al Gore came out with that time about climate change ...that man should if been taking out for all that bullshit he spread as ever since it spread like a wild fire ....aaaaah crap I'm ragging now just after writing this once again !!! But it's true what I'm saying ...give it 10 years mate and you won't be able to drive your v8 no more as you won't be able to buy any octane for it just wait you see. Enjoy it while it last guys ...enjoy it while it lasts 😭😭😭😭😭😭
@@ger808 No, the point is to turn those additional carbs on/off depending on demand.
@@ger808 You're right. The goal is to force gasoline out. There will come a day soon when certain countries/states/cities will ban the use of fossil fuels.
The reality of the situation is that there is not enough electrical energy (never mind CLEAN electrical energy) to support putting transportation energy on the grid. California has regular rolling blackouts because they can't support existing demand. My state has only 11% green energy with no prospects for changing that (The wind doesn't blow that often and there are about 3 sunny days per year). The math simply does not work. No government entity has explained where this additional energy is going to come from, but they make all of these ludicrous commitments.
The goal is not to replace ICE vehicles with electric vehicles. The goal is to get you to stop traveling.
However, there is another possibility. It is standard for corporations to blatantly lie about their capabilities and to demand tax payer funding under the guise of "climate change" and "safety". In 10 years when it can no longer be hidden that we can't support transportation demands with electric vehicles and green energy, vehicle manufacturers will just say, "Oh darn, we were wrong. We need to keep producing ICE vehicles." But by that point they'll have collected TRILLIONS of dollars in government funding.
There is no incentive for any corporation to tell the truth here. It is extremely lucrative to jump on the clean energy band wagon.
Green energy is a scam to bilk tax payers for money and to control their mobility.
Excellent I can't believe you made it work so nice and made it look like it belongs there. If you did this I believe you can probably make the small carb work on cruising and add a 4 barrel carb together and make it only work wean you get on it Looks like you have more space for another carb towards the back of the engine engine try to make it work if it's possible I think you can do it. 👍👍👍
Hi. This was an interesting 1 hour+. Most lawnmower (carbs) I have tried work with e85. You could also try ethanol (blends), which produces a leaner mix. Blocking the radiator helps retain some of the heat of the engine, to get into efficient burn zone. You also noticed, the vacuum in the manifold is deeper. Thus, the initial pressure starting the compression stroke is lower than with a big carburetor. Therefore, your engine is running Atkinson-cycle. You noticed it yourself from a quieter exhaust note. With normal timing, there will not be knocking, because the initial cylinder pressure is lower. Thus, to get even better mileage and increased horsepower try advancing timing (even more with e85. Until the point of knocking). Also, lowering the head could give better efficiency, to be in par even with stock cylinder head pressures. If you do that, instead of 41mpg, you could probably do 50mpg .. MIB's helicopter heist 80mpg..
By gosh it looks like a really good MadMax setup especially after they drop the NEMP on us That's really just a stupid simple setup 👍
I'de like to see Engineering Explained and others do some independent testing on this great experiment
I knew an old guy who told me about old carborators getting 60 mpg then that old tech was bought and hidden from public use. This video makes me believe him. Most excellent video, thanks man
Yeah I'm almost certain we had the knowhow to have far more efficient vehicles long ago but to keep the industry neverending advancements get put out in a planned order. That and planned obsolescence will keep us buying cars for many decades to come.
My 2018 GMC half ton crew cab 4x4 with the 5.3 gets 30 mpg on the hiway at 60 mph and has tons of power , I had a GM sprint with the 3 cyl many years ago that got 75 mpg on the hiway , the manufacturers have done a great job moving a lot of weight with the power that people want .
This is great stuff! I'm curious how much bigger of a carb you could run before a accelerator pump would be required. That accelerator pump dumps a bunch of fuel, constantly in use on the street. Your enginuity and unexpected results are a beautiful mix of doing what you love! I'm looking forward to where this awesome insanity leads you. Keep it up! I'd be a buyer!
If a guy with a garage and tools imagine what a billion dollar company could do providing the government stay out of the way
