- this vintage well built Homelite gen set was donated to us after sitting in a new england shed for 20 years, the kicker is it was stored with Marvel Mystery Oil when it was put away, so lets see if that helped to preserve it.

How many men wake up early before their family and drink coffee on Sunday morning while watching Mustie1?
I can only say it is probably "many".
Guilty…minus the coffee
I had hunting issues with my generator and didn't know what to do until i stumbled upon James Condon's channel and know i know more than enough
The tip of the needle should be Viton , the name DuPont gave for a rubber that is not affected by gasoline . Great job here , fantastic work . !
@Mustie1 Try this... Heat the plastic tube from the carb cleaner spray with a lighter (about 1/4-1/2 inch from the end. Then pull on each end of the tube to stretch it. This makes the outer/inner tube diameter smaller and more of a pin point. When the melted plastic solidifies, use small wire clippers to snip the tube at the smallest diameter that still provides flow when spraying. The cleaner comes out like a pin point pressure washer!
You can also do the same to create 90 degree angles in the plastic tube to spray sideways inside long tubes.
I used to make/keep custom tubes around for these situations. Hope this makes sense. BTW.... Great videos.
This is brilliant!

Thanks. Hope it helps.
Comment of the day right here
That's an awesome tip! Thanks
I've been watching you for a few years now and I've learned more from you than what my school I'm attending right now has taught me. Definitely keep up the good work!!!
Easily the best New Hampshire RUclips channel! You make us proud brother!
This video made me think of my Dad and smile. He used to have a Homelite chainsaw that he called a troublelight. It was always trouble to start, lol. Thanks for the memories. Keep up the good work. Love your channel.
Nothing better than a Mustie1 video early sunday morning
I wish you all a Great Thanksgiving Day 🙏
Darren, I've never heard of using MMO in the tank and the bowl. As a mechanic, we would simply drain the fuel and empty the bowl for storage.
For real, way too many products to try and mix in when you really just need to remove the fuel
I run a bit of premix through and drain that.
Bit of oil combatting the ethanol isnt a bad thing in my opinion
I've used MMO as a "last run" mix. Run it with a fat mix of MMO. Never had issues. Straight would be bad though, MMO alone gets gummy when it oxidizes.
If the equipment sits a long time just the moisture in the air can corrode the metal. So an oil coating can help then.
in most cases yes but just like with boats you use fogging oil just leaving a empty bowl still allows moisture to build up so yes drain the tank and bowl but use fogging oil afterwards
Such a great tutorial and explanation of the product!! Very patient and interesting approach to figure this out. Too bad about the gas tank situation but overall, a terrific shoot. Funny how you chuckle several times where others would be less jovial over the frustration 😆. Glad you took this challenge on for us all. Thank you! 😊
Thanks for all the awesome videos. I always look forward to the next new one you make. I’ve learned a ton a useful information from them. Keep up the good work.
I started watching your videos years ago just out of enjoyment But I didn't realize I would learn so much By watching your videos and videos like yours thank you.
Muskie that was a great video never miss a video loved it never miss a one thank you for sharing and your time was great.
Your carb knowledge is astounding.
That has to be a record for the amount of pulls to start of anything you have fixed. Love the videos.
As far as oil level goes, many of the newer engines you need to check the oil by just placing the dip stick against the opening, rather that screwing it in which , if you screw it in makes the level appear higher
Good Job Mustie.......Like your generator repairs!!!!
No good deed goes unpunished: Ain't that the truth... hope they learned something. Probably not... It's fun to look back and see how generators have changed over the years. Great vid Mustie.
I think you're right about the manufacturers playing with the specs. I just replaced a 1976 Sears 1/3 hp garage door opener with a modern Genie 1.25 hp unit. The Sears was built like a tank but the Genie is 1/3 the weight with almost 4x the HP. I don't think so. The Sears lasted 46yrs. I doubt the Genie will even get close.
My Genie like to ignore my close door command so much for "Always At Your Command"
The original was likely made of steel and with heavy guage wiring. The. New one problem uses Aluminum and thinner wire (with better insulation) allowing more turns yielding higher power with less weight.
The difference in the gen head vs the sticker could also be running watts vs starting watts. Typically starting is the advertised number as it is slightly higher
Good videos, I learned in college something that gets overlooked. Behind the choke plate there are usually 3 feeder holes for the idle circuit drilled @ a 30° angle @90° to the choke plate shaft. This supplies the idle with choke closed and feeds fuel @ all speeds. These are mostly overlooked and covered by welch plugs on the outside ( like a techumish carb.) But are on most carbs but are very small!
On the Honda EU2200i generators they are almost invisible. Tiny holes all over that carb... Take some time to look everything over very closely. Mine was clogged dysfunctional and I got it working again with nothing but hand tools and some carb cleaner.
Thanks for the vids brother. My Sunday morning routine is a hot cup of Hawaiian Java and your weekly repair video. I’ve learn a bunch about small engines and mechanics from you.
As several have noted, the solenoid mechanism is powered by the generator circuitry, rather than the engine. Quite possible that some or other component of the generator has degraded, over time, (I'm thinking slip rings) and will improve as it is run. Could be several things, but almost certainly related to longterm storage.
I suspect the switch has bad contacts.
I also suspect the tweaked spring at 36:08 plays a role.
as a tip, you could steal the common tip set from Refill canister for butane lighters. those tips fit the brake cleaner bottles and a like for letting the tip narrow just enough to fully blow in.
I guess what this shows us is, filling it with marvel mystery effectively takes a photograph of the state of the cárb before it was put away - it didn't get any worse after all that time... but it doesn't make it better!
I learn a lot watching the videos Mustie1, awesome content. 👍👍👍👍
I saw a speed handle being used!! Takes me back to my flightline days. Great video.
Same here. USAF machinist, 83-96. Removed many stuck screws with one.
@@garymallard4699 you were flying. Just different machines. I rode and owned many bikes back when. The one I wish I'd kept? My Kenny Roberts RD350. The granddaddy to the modern crotchrocket. Too old and busted up for that now. I just watch the races on You Tube.
I have a 1/2” Craftsman speed wrench that my dad gave me. His dad was a mechanic and used it when he worked at a Chevy dealership after WWII. It is one of my most prized possessions.
Howdy George! Thank you for the wonderful toys...we love to see Mustie1 working on this stuff :)
Such a down to earth guy. Love watching your videos :)
Thanks for the video! Makes my Sunday mornings interesting.
One of the only owners who show any respect for his gear. Nice!! Still that was a heck of a job
Great video glad you posted keep them coming thanks
That vice-grip gas tank made me giggle! That hunting idle is a puzzler!
I drill out the center hole on the idle jet using jewlers drills one size up from original when I run into a hunting engine. Its time consuming but this works 100% of the time for all engines. Had to do it with a BRAND NEW snow blower that hunted like that from the get go. Even under warrenty, they couldn't fix the problem. Went up 2 sizes and it fixed it. Owner says it runs perfect 2 years later.
Good option also.
The problem with newer machines is the emissions tests, they run to lean these days to pass those.
what surprised me about my new snowblower that i bought last january is how little oil it takes for 250-ish cc motor. It was Not made to last so I am going to change the oil 2 or 3 times during the winter. I haven't ran it a lot but I may go up a size or two on the jets depending on how the plugs look
I had a new Honda Motor that did this. It drove me nuts now I know.
I think it's oil in the passages. The surface tension of oil is MUCH higher than gasoline. I think it needs a proper cleaning and it is NOT a jetting issue. It worked fine when it was put away.
I clean the gas tanks with industrial white vinegar. I love those Robin/Subaru engines.
Mustie1 video early sunday morning here on the west coast, all is well. txs for sharing
Another great video bro. Safe travels up your way
Good sir :) I recently had my trike stolen and destroyed. I am retired and disabled am only able to insure for 6 months of the year. This was an error as I now have no trike. It was a 1500 dual port with a built frame and chassis, with a body kit similar to yours, except mine was black and purple. I got to thinking about your set up and I remembered watching your VW build from quite a few years ago and decided to cheer myself watching it over again :)I remember saying to myself, how much better you would have made it had you had the equipment that you have now. Please understand that I am not begging as if nothing else I still have my pride. I love your channel and wanted to share my thoughts. Sadly even though you are across a big pond you are my escape to the outside world. I comment rarely but I always watch.
Perhaps a better needle/bowl comparison would be a toilet bowl valve rather than a bathtub drain. Great videos, Mustie. I look forward to them every week.
Yup, like a toilet bowl. I have always been impressed at how effective that needle & seat arrangement is. Merely from the pressure of the rising float pushing on the needle, gas gets stopped in it's tracks. Yet preventing liquid flow in numerous plumbing efforts (garden hoses fittings, etc.), it often takes some serious tightening effort to keep water from seeping past the gaskets, teflon tape, etc.
LMAO. I thought George was a ventriloquist at the beginning of this video. It looked as if he was doing the introduction without moving his lips. 😂🤣🤣
scared the carbon outa me..
Ah! Sunday afternoon and a Mustie1 video. Now coffee and everything is perfect :)
GOOD DAY MUSTIE1. you are a very patient man, this gen. is running good now. keep up the videos comming. GERRY G. from canada.
Great video. I wondered if the solenoid was loosing its magnetism when the generator was slowing down to idle because it was so old? Maybe with some run time it'll come back some, but probably would need to be replaced. Thank you for all the detailed camera work. Always enjoy these videos.
When testing one of these castoff generators, be aware that one of the generator failure modes can be a disfunctional regulator circuit. A neighbor started one of these he bought somewhere in the early 2000's. It was producing 300+ volts and had burned out several items in his house before he realized something was going wrong.
I learned a new expression, ‘hunting’ from you. On my lawnmower, I disabled the governor because of hunting. It has one of the Briggs engines, and old carb, no float.
Another save by the Master. Is it possible the magnet in the idle circuit was so corroded it wouldn't function properly and running it actually cleaned itself? Another great morning with Mustie, have a wonderful day. 👍
Exactly my thought, it running made the magnet essentially polish itself by making it work as it should
That certainly got the head scratching that hunting amazing sorted itself out 👍
I really enjoy these small engine repair videos. Although it's unlikely I'd ever need to try and fix a [modern] car engine, I could see circumstances in which I might need to fix a small engine here or there.
Your mission (should you choose to accept it), is to do a video on available basic supplies (e.g. O-ring kits, tubing, gasket material, springs, air and fuel filter material, cleaners/solvents, etc; including their sources) that someone expecting to have to repair small engines might need to have on hand. Thanks!
Dang I have an old gas powered drill that's the twin to that trimmer. I may have to try and give it the *Mustie1* treatment (with all I've learned from your 1000+ videos)
Always good to see you.
those a great little engines i have the same one on my old Mantis mini tiller , engine made in Japan
a gas powered DRILL? I bet the wife gets upset when you fire that up to put up shelves in the pantry.......
@@muskokamike127 gas powered drills were used on remote sites before battery drills came along. Power company linemen used lots of them in remote field locations installing power lines and poles. They are great machines and very useful.
@@rogerjustice8835 yes, I realize that, but you sure didn't use them to put up shelves in the wife's sewing room lol (which was the point of the joke)
@@muskokamike127 lol yes momma would not be happy, and when momma ain't happy ain't noooooooo one happy.
Old generators are the best. Nice job getting it going.
Wish I lived near you, I have a 25 year old 5000 watt generator with 10 hp. Briggs, never run, never had gas in it, was in my basement 15 years and my garage 12, health won't let me work on stuff anymore, oh well ! Love yer shows !
Thank you Mustie for entertaining us!
I have an old homelite generator. I got it for 150 bucks. The original oil looked like honey. All I had to do was replace a 5/16 fuel line and it works like a champ. God bless
Loving the T shirt very apt in this day and age and so very true!
Definitely the longest 2 pulls I have ever seen! ;-) 😁
I always explain to friends that carb float bowl works like a toilet bowl tank of sorts
makes me wonder if the hunting is due to a dirty start run switch, the more the switch was worked the better it got. great vid as usual.
Good Job Mustie1. Consider that all carbs work off of Barometric Pressure. Baro differential is what allows the fuel to travel up the emulsion tube against gravity. When you see a float bowl with an 'O' ring style gasket, its very important that the O ring seals. That leak at the bowl could be where your rpm surge is coming from. Again, Great Job and Great Camera Work!
Bought a used building site Honda generator in 88, run and off grid yard, site work and all night parties for years.
Changed the oil, filter and plug regular, it will still start second pull no matter how long its left.
Cheers
Hello !! Mustie1 , Thanks I've been watching your Show It help me a lot how to diagnose any Small Engine to proper check up ... From Hinton , Alberta , Canada
As said before, old-fashioned engineering screwdrivers shank was filed the same width as the blade. Carpenters were cheaply hammered flat so were tapered to the point.
Wow Your videos help me all the time
I love your videos, mostly because I have been fixing small engines for 40 year's . Although it's informative , I notice that almost all the mechanics even large engines like cars & trucks , all shy away from taking off the carb & cleaning it . If it's been untouched for 5 , 10 , 15 , 20 + years just take it off and clean , and kit if necessary. It isn't a time saver to leave it on and try it then end up taking it off or off again to clean . They are usually abandoned for a reason and I've found a carb issue is about the #1 cause!!! I'm not getting on you but personally, I'm just saying don't be afraid to take it off and clean it !!!!!!
Have a homelite 4400 I bought back in 2000 and it runs as solid today as the day I got it! Briggs 8 horse and solid generator runs circles around the off shore crap you buy today. Of course I maintain and run at least every 6 months with a load. Cheers!
Between you and Steve's small engine repair channel i have been able to get most of my old toys running again. Now i sit and look at them wondering what to do with them lol
Great learning video as always. Thanks
I want a air table so bad! Great video!
Now I know more about governors. Thank you..Mac
Love your videos man!! :)
good job Mustie!!! Awesome!!
...good one, keep safe and have a great week..
Always an educator. Every post.
Probably just needs a good run 👍 Guess its a pretty new machine 👍
Nice video as always. Thanks
Half a million subscribers you don’t read comments but this is good stuff I learn here
Pat Ward , racecar driver, used to get old engines running again.Ward and Dempsey used to make gocarts and minibikes. Mustie reminds me of those ace mechanics,, back in 1974.Finger Lakes Region of New York State.
I've had a few. At Home, Light Duty. I used them commercially, and they worked fine, but not meant for all day hard use.
I’ve done the back feed trick with a drill chuck. Interesting trick I was surprised it worked too. Of course it was taught to me by an old high school shop teacher who knew a trick or two
Yep, "flashing" the field windings can work on many brushless generators that relay on residual magnetism in the field windings that has decayed due to sitting for a very long time or being powered down with a heavy load attached. Modern invertor generators and even older synchronous generators that use a different setup like brushes don't rely on this residual magnetism so it won't work on those but is a good trick to know :)
You get some awesome stuff then I learn how to fix them thank you two thumbs
Love these small engine videos
Here's Eugene's back yard repair tip for those jet passages. To clean them.out without poking wire through them is heat. A torch will sometimes cause that shellac to turn back to liquid and run out. I did it on a honda 3 wheeler because passages were too small for a wire to go through without bending.
Great video
Thank you for sharing. Enjoyed.
Have never heard of filling up a carb bowl with MMO for storage. Looks like it worked pretty good.
I wonder if maybe there was a stiffening capacitor in that circuit that was reforming causing the magnetic field on that solenoid to fluctuate. I imagine that there would be one in that circuit to dampen the transition from running to idle but immediately transition from idle to running when a load is detected. When electrolytic caps sit many years, sometimes they will act as a dead short and have to be run to reform and start working again... Other times they pop and let the smoke out
Fogging the cylinders and having clean motor oil is important for long term storage. Best if you rotate the crankshaft every year, also. I lost a 4 cylinder motorcycle from galvanic corrosion of the pistons in just 18 months of non-use.
Seems like the load sense circuit was ultra sensitive and causing the idle solenoid to oscillate on and off. I noticed simply plugging the tools in (without turning them on) was enough to kick it back into run mode, that seems sensitive to me. Another great vid and project Mustie1. Thanks for the content.
As you mentioned, non alcohol gas helps a ton. I have two outboards made in 56, and two in the 60s, when they started selling the non alcohol, it was 87 octane, a few years ago they boosted it to 89, made a big difference in those old motors. What I've been doing with all my small engines is mixing with Marine Stabil, and have had no more trouble.
I had a real bad air passage clog. The carb sat for 15 years with ethanol gas. Numerous ultrasonic baths and overnight carb soaks didn't touch it. As a last resort before buying a new carb I boiled it on the kitchen stove for an hour with a tablespoon of CLR. To my amazement it freed it up. Runs like a top now. I think the heat expanding the carb is what allowed the crud to free up. Funny enough I have that same generator.
that has a good motor on it, Wisconsin Robin engines are industrial grade.That solenoid bracket looks bent, I bet if you straighten it the idle function will work properly again.
Another Sunday afternoon sorted
awesome video
I enjoyed it, thanks for sharing
I suspect that if you had measured the voltage initially that it would have been low, that the exciter capacitors had lost their forming and that as the engine speed fell off the voltage got too low to to hold the solenoid, and then with run time the capacitors regained forming. With full excitation, the voltage would still be high enough at low rpm to hold the solenoid in. Just a guess.
Yeah, it looks like there is a loss of power at the coil or it never gets power at all. I think there is a board behind that panel on the front. That is if the coil is just meant to hold it at idle until the circuit sees a load.
What I like to do with the gas tank is just thin down some gas about 50/50 With clean cheap motor oil. Then dump it out and the gas evaporates out leaving a micro coating of oil. Store in a conditioned area and they last for years. Often use this on motorcycle tanks after electrolysis
You hit the nail on the head. That's exactly why it started healing itself. There have been many of these older generators thrown away because the generator head was supposedly shot and had low voltage and frequency when all it was was a blown exciter cap.
Thats what i think happened too, It just needed some run time to reform a cap. I think it may have been a stiffening cap to dampen the transition from run to idle.
Ian, I like it. I was thinking, get a meter on those wires to the solenoid. I suspected it was losing juice each time the engine surged.
Great way to start a Sunday !
Excellent video Mustie 1 :) also agree stuff built back 30 plus years ago and tuff made last long time too and new stuff may get 10 years on small engine also built war too! Also worth have old stuff for years and baby them to last forever! I know my late Dad used say love old and going keep tick tock like old Grandfather Clocks do Lol! Also he did most plus got his 2 chainsaws running nice shape one is Red Homelite with 16 cutting bar made heard 1980's & other is Yellow Color with 18 cutting bar it a Skil electric tools company but made 1966 to 1970's year from Winnipeg Manitoba and both thumb oiler oil bar up! Not sure CC are but powerfull for mix gas for 30:1 to 50:1 can used on them !
Keep up the good work
happy day lol not one but two carb teardown on one machine HEHE, get rid of the "1" and rename it to Mustiecarb, Gotta respect a man that cares for and properly puts away his toys. Cheers George.
The problem could be that you have your heat gun plugged in an d it could be putting just a bit f a draw on it causing it to kick up I l know my honda generator will not kick down if something is plugged into it just a thought of what could be causing the surging problem. Great videos keep them coming
I pull mine out of storage and test it every year, as you should. After wards, I clean out all traces of fuel and hose everything down with PB Blaster. On all my snowmobiles, I found it best to drain all the fuel out of everything and used WD -40 or an actual engine storage spray. As the fuel pushing on the needles caused the springs inside the needle to get weak over time and cause flooding issues. Anyone storing an engine needs to use something designed for storage, not Marvel's Mystery oil. I have found carburetors completely plugged up with straight fuel stabilizer as well. People dump it straight into the tank, thinking it will mix or do not bother pre mixing. It does pickle the carburetor, but requires cleaning because stabilizer gets thick over time, and eventually dries out, making a HUGE mess.
The issue with it hunting for idle: every generator I've ever encountered, even brand new ones out of the box have done that....until you put a load on it. I was on the job site and the power went out so the site boss ran off to the local building center and bought one....not sure the brand name but it was a brand name, fired it up and it did that.
You are correct ever once I owned once loaded it stopped seems that's how they work.
