PLEASE KEEP IN MIND when you are watching my videos: I am showing you the least expensive, quickest "backyard" methods for repairing or servicing your lawnmower. Replacing all components such as gaskets and fuel lines is always recommended when rebuilding or repairing equipment. With these videos I hope you are able to fix and repair your lawnmower yourself with minimal parts, knowledge and tools. Thank you for watching!
Very complete and helpful vid. Its amazing how sensitive these small engine carb ports are to corrosion/contaminate plugging. Draining the gas and running them dry for storage saves a headache for sure.
Great video. I just finished cleaning my carb on a 3250 generator. Your video got me through the process with no problems. This is the first time I've taken a carburetor apart. The generator started up with the second or third pull and ran smoothly.
Man you just saved me a lot of headache. Main jet was clogged. Cleaned it up along with emulsion tube and cranked on third pull. Thank you so much for making this video. I owe you a beer!
Excellent!
I ordered a new carb for mine. I got my old carb off and the bowl and float were pretty clean but the jet wouldn't come loose. I pretty much destroyed the jet trying to get it loose. So now I'm glad I ordered the new carb.
One of the better on-line instructional videos I've seen. Nice to hear correct names used for small parts like main jet, emulsion tube, float valve, pilot etc. Couple cautions worth mentioning though. When cleaning/clearing the the tiny orifices that empty into the throat as well as the single on the intake side of the throttle butterfly, you really need to spray cleaner with straw attachment and only spray from the inside out...same with compressed air. Those are the bottleneck of the fuel system. The gunk you so often see is a combination of ethanol residue (through striation) and polymeric residue. The striated ethanol after exposure to air (usually through the ambient pressure port) eventually takes on a crystalline structure and with all those sharp edges to bite into the soft brass, well, flushing with pressure from the wrong direction can be more than counterproductive. Also I'm sure you wet and twisted the Q-tips to avoid "fiber drop" but your viewers don't know that because they didn't see that...just saying. For all it's worth I like tapping my wire strand reamers with a hammer to flatten them and create a sraping edge. I've knit picked you (it's easy to do and I'm good at it...lol) but truth be told this is an excellent presentation and you are to be commended! One last thing...I promise...really...Those are NOT 10mm bolts, studs or nuts...they are 6mm fasteners that require 10mm tools. I know I'm overly critical and for that I apologize.
This is very useful!!! My Generac generator was sitting with fuel but good thing no corrosion in the carburetor but there was spiders in it lol. Anyways fuel lines and fuel in the gas storage is been drain and ready for fresh fuel.Thank you!!!
Your video just helped me get mine goin again, thanks for making this video
Glad I could help
Nice job Jeff: I had the same carburetor in my shop last week that had pinholes in the float bowl. Great Gasoline (not) Also had water in it. I cleaned it and put a new bowl and needle in it and it ran great, like yours did. Thanks for the video's.
Great video. I just had someone bring me that same generator today. Same issue. Thx
Awesome video, I like how you show every step and detail
Excellent video Jeff thanks so much
Thanks a lot for your time and instruction. I learned a lot as well.
Glad to hear that, thank you
Mine had a little gunk, I wiped it out and it started on the first pull. Thanks!
Good video man it help me out with my generator. With the hurricane come at us here in Florida
Stay safe friend
Thanks for a great job my friend. I need to get mine out and clean the gas out of it
Great video Jeff! I have the same one I bought at a yard sale for $20. I have it running fine however it does not produce power. Any thoughts on what might be the issue? I can't find a reset button anywhere on it. Thank you!!
There should be a reset somewhere on it
@Jeff's Little Engine Service Thank you! I will look again. I plan on testing from the outlets and breaker to the avr and brushes. I don't see and bad coloring of the windings do I remain hopeful.
I did like your video thank you for taking the time to put it up.
I have an Einhell generator looks very similar to this one in positioning of carby, filter etc. Watched a different video yesterday but they didn't talk about the slow jet 9.35 min into the video! So guess what! when it didn't work I searched again for and found the best helpful video in youtube land! Took everything apart again cleaning the slow jet and found that the orings had perished. cleaned up again assembled and YIPPEE it worked beautifully! THANKS JEFF :) Will this be OK going forward without those orings? Or should I purchase new orings? Regards Paul
if it works, run it! I don't think the orings are available seperately
Good video make sure you include the chickens like to see how they’re doing
Nice "Long Johns" at the 8:00 point!!! :) Love your channel, keep 'em coming.
I had carb problem...tried cleaning it 2 times and it didnt work...bought a new carb on amazon for $13 ...runs like a charm...but from now on I will run it every 3 months and remove all gas .
Thanks I have a Generac Generator that's not been run since I've ran it years ago , but I ran it till it started spuding - and hit the choke and it should have sucked all the fuel out and burned the gas up .
hopefully . If not when I need it all I'll have to do is throw gas in it - if not I'll use this video . Thanks
This video was helpful .i subscribed to his shop
Nice video, thank you 👏👏👏
Awesome repair lesson!!
well done Jeff
Thanks!
Cool, good work, that looks like a CHonda
lol! "Chonda"
Jeff. My brand new Generac 8000 watt starts electrically no problem. Ran It fot 4 hours tested running house via inlet box.
Just put 3/4 gallon of gas in. Oil level is good.
Problem is it wont PULL START.
ANY THOUGHTS?
Not familiar with Generac's system but possibly the key switch for the electric start needs to be in, and remain in, the "on" position...even when using the recoil. How do you shut it off? Is the "on" position shared between both modes? Just a thought.
@@dalelange845 hey, Thanks. Before your reply I had a brainstorm. Lets make sure my switch in in the "ON" position. Yeah that was it. My switch is 3way. Start,on,off.
LoL....gotta laugh at myself before beating myself up!!!
Too funny. James, I almost left it alone. I was thinking "he'll figure this out" and then "he's already got it". The only reason I tossed it out there was as a final goal for myself to reach to be able to call it a day, a very long day, and then i could put the phone on the charger and finally get some sleep. Anyway, just taking a step back for a moment away from the frustration seems to work more often than not...maybe it just breaks the pattern of thought that overshadows the simplicity of the solution, if that makes any sense. Lol
Good to know you actually already had the answer and just needed a moment to let it find it's way out...funny how the universe works.🤔 I do equipment repair (both ag. & construction) and here's an equally bizarre phenomenon; I can go a year without working on a 545 Ford loader then I'll get hit with 4 of them at the same time with the exact same problem. Wierd...and it happens ALL the time. Anyway I wish you the best and appreciate your update.✌
Great Video. Next time clean out the Tank, Fuel line and Pepcock.
Good tip! I forgot to clean the petcock bowl....
I would not recommend touching the petcock. It is cast metal and mine shattered like glass when I tried to remove it. I was thinking there might be a strainer that should be attended to.
Great video, Jeff. Would you be able to tell me the model of generator you have there. I have the same one and the sticker is missing. I would appreciate it.
sorry, it is no longer in my shop
The model number is ( 005790-0) , HOPE that helps ya.Here's a address too, (Generac power systems, INC. P O BOX 8 Waukesha, WI 53187 PH # 888 Generac 4363722 FAX 262 544 4851
Awesome. Im gonna clean my generator
I stripped out the soft brass main jet w/ a screwdriver and it's stuck inside the carb still. How can I get it out now? Thx for the help.
you will have to extract it with an extractor
A small easy out. Spray some lube in the cavity and let it sit overnight. You might also try (really) sharpening a small steel chisel and giving it solid wack or two. Either in the old grooves or make new at 90°. Either way use the widest chisel that will fit in the cavity (max torque). If that doesn't work and you cant catch a thread sometimes gently driving it counterclockwise while at the same time applying more pressure on the opposite radius with a small punch will give the chisel side just enough to start a thread. Then there's always heat...if you go this route make sure there's no left over lube, solvent or gas that will catch fire...and ONLY heat the outside of the pick up tube...you want it to expand while your main jet remains cooler than the tube. If you are successful using any of the above remember to run a tap down the tube, obviously with the emulsion tube removed, and run a die around the main jet before reassembling. If you are able to re-use the main jet be sure to clarify the screw driver notch with either an electric cutoff wheel or even a hacksaw so that the screwdriver you plan to use fits that notch both snug and deep. And next time remember to use a round shanked screwdriver that fits proper...brass is super soft. Good luck and I hope you repost with your results.
We solved the carb problems by turning gas shut off valve while motor is running which in turn empties the carb until the next time you need to use your gen, it's a simple solution folks !
Did that. Even added a gasoline preservative and it still fouled.
I really like the video, because I have the same generator, and left it sitting for a year. lol Well ,I followed your instructions and advise and was successful in doing a good reconditioning of the carburetor and fuel system. I love the chickens you have, we call them FRIZZLES here in Florida. They have a personality of their own. lol, I don't know how many or types of Appliances this 3250 will run. But just glad to have it running anyway. I guess I'll have to sit down and figure out how many watts each and every Appliance draws. So far we've powered a refrigerator and a Fan to keep from burning up during a Hurricane. lol Very Glad you're doing videos , you make it so simple to work on engines, YOU"RE A GREAT TEACHER. To Bad , I can't be a neighbor of yours , every day we could drink coffee and work on engines together, we would get some of the best free labor a body could get. lol Take Care.
Thanks friend. I love my chickens!
Great Video. Thanks and keep it up.
Thank you
That plastic screw doesn't adjust the idle, it only keeps the pilot jet from coming out. Many of those smaller carbs have no way to adjust the pilot jet beyond replacing it with a different size.
The engine of this type is actually a subaru 4 stroke engine. I have this similar motor to generator and also mower (ryobi) i found the schematics for these engines. they range from 140cc-190cc and be of many CC's engine type to which model and torque. Unfortunately, the carbs are usually good. but its the tanks where the fuel sits gets seriously dirty and most areas to air get rusted very quickly.
where can you buy the pilot jet? I can not find a source> not even generac corp. I did find a carb at amazon.com. but no slow speed jets. my slow speed jet had a broken o-ring...had to buy the whole carb for $25. Found it by carb brand name and wattage GP3250. it was a viable solution, but I did not need the whole carb, I only needed the jet with the o-rings on it.
I'm in the same boat at the moment as I need the size of the orings for the "pilot jet", I'm assuming. I wish the video would have been edited to say that it shouldn't be put in the carb cleaner bath before and not after. Anyone know the size of those orings? Looks like the pilot jet has "45" on the top which may give some idea of size but I can't nail that down via Google searches.
Are there any metal parts anymore. Where were the chickens?
Nice work Jeff she's running like top. Oh where's the CHICKENS
Thorough job.. 👍👍❤
I like you channel .nice work .
thanks!
Nice
Why do you guys never install an inline fuel filter, when you have these things apart? They are cheap, and easy to install.
Do you know the part number to the float bowl gasket
Thank you 🤗🤗
Ethanol Disorder .. got stale and the ethanol/water stratified (separated out) & sunk to the bottom ...
Non ethanol gas is available where allowed .. i.e. Walmart/Murphy “blue hose” is ethanol free ...
😁👍
Oops * Stratified ethanol * 16 hour day and I'm turning into a zombie. Lol
85%-90% of the problems I see come through our shop is fuel/carb problems.
yep same here
The camera is jumping all over the place! Getting motion sick! LOL Great job though!
👍👍👍👍👍
Generac looks just like my china made Harbor Freight generator.
Why pull the bowl off if you’re removing the carb any way, that’s how shit gets lost.
If it is not that dirty, sometimes all you have to do is clean the float bowl.
Hey papa that's an unfair question...Jeff was hoping to not have to pull the entire carb...trying to be as fair to his customers as possible as I'm sure they are paying hourly. Just curious, who conviced you that completely disassembling something had a direct correlation to losing parts? Do you always lose parts? Or did the person that mistaught you that illogic have a problem losing parts. Father, brother, boss? Oh well it doesnt really matter but obviously there are some missing parts...somewhere...and you got blamed.
Honda in disguise or chinese honda
Haha...also the most prosperous!!!
Curse you Ethanol.
CURSE YOU ETHANOL LOL!
