Generator help

[RonMexico]

Purchased this generator off Craigslist 3 months ago and it wasn't running, sputtered for 5/7secs after we dumped the tank and added some fresh fuel, so I decided it was worth the risk. I rebuilt the carb twice and changed the fuel line and fuel filter. In the two video it runs for about 35-50seconds and the longest it's ever ran is 4mins. Should I sell it(my cost $275+ 25worth of parts) or have a professional look at it?

Can am anyone help me trouble shoot this generator, or does it sound like it's not getting enough fuel?

Don't see the videos. See if you can locate a new carb on Amazon or elsewhere. That will generally cure a fuel problem.

Try running it with the gas tank filler cap off. Maybe the tank vent in the cap is plugged. Long shot but it popped into my head.

Good luck on it.

Looked into it but I'm not paying $95, rather trade or sell it

Sounds like a needle and seat issue. It may be stuck so gas is just trickling into the bowl. And when it sits long enough the bowl fills up and then it will start and run until the bowl goes dry again. Old gas can create vanish when it evaporates and it is very sticky stuff. Did you soak the whole carb in cleaner when you did the rebuild. Some of the small holes or venturi's can get clogged as well.

What carb & motor?

One way to reseat that unit is some ashes. Use it as a lapping compound to clean up any wear spots between needle & seat. But first look at the needle, that rubberish part van be trashed. You also need compressed air, like Big E3 mentioned, those passages need to be free of any particulates.

When you replaced the carb - manifold gasket, was it put on correctly. Regarding the carb, if it had any whiteish residue in the bowl area, you'll end up replacing the unit. That "corrosion" is seen in the bowl area has probably worked it's way in to other areas. Did you remove the fuel mixture screw and clean it out.

Invest in a honda generator. Quiet and they last forever... They are also expensive

Will you please Explain in detail what you mean by rebuilt the carb?

Was there a yellow hue to the inside?

They was a lot of gunk in the carb. I took the carb 100% apart and assembled it without using any new parts but the float bowl gasket was a little worn so I purchased a few gaskets and two more cans of carb cleaner. I went to town on it once more and installed the new gaskets. The needle looked fine but I didn't replace the needle but I am thinking that will be the last attempt at fixing it fix. Overall ,it runs about 1 minute but chokes out"(try's to keep going but dies).

ONE KEY NOTE: I have to add a little fuel through the top( intake with filter removed) otherwise it won't start. With all the help I am now thinking the needle isn't allowing the bowl to fill properly.

Thanks bro but I only have $300 and about 12hr invested in this generator, shopping Honda generators I would have to add $800 more for an equivalent output.

This was the manual I found online.

Yes I think you're on the right track. Recheck the needle and jet along with clear the passages

Will do and thanks to everyone who gave me help and suggestions.
I found the needle for $33 online, so while I don't want to buy a new carb it's hard to justify spending $33 vs a carb assembly for $95.

This may be a dumb question but the needle looks like one that was in my 78 351M... Can I swap another needle from another small engine?

As long as they fit they're all made in china

If I left my old gokart sitting too long (like over winter) without draining the tank, I used to have to pull the carb out and give it a good scrubbing, including polishing up the needle with fine sandpaper or steel wool and picking the jet clean with with a needle to get the gunk out, after which it'd start up and run just fine. That was before I learned about gas stabilizer.

Sounds like "idle jet" is clogged. I had this on my motorcyle. It is a tiny jet and the only way to clear it was use a wire plucked from a stiff wire brush and poke it through the jet. Solvent would not clear it. The jet lets the engine have fuel at idle speeds. When the throttle is advanced the fuel comes from the main jet.

Many generators have an cut-off to shut down the motor if the oil level is low. If yours has one, disconnect the wire from the oil level sensor and see if that helps.

Thanks for the tip and suggestions
