3 year old unit, 10HP (Tecumseh) Powermate Generator, 6250 Model. Will only run under full choke. I see no visible air/fuel adjustments, is there any? I'm presuming the carb is dirty and needs cleaned?

Hi,

Please check for spark fuel. Please double check that the generator isn't in extremely cold temperature when you're running it. After making these adjustments, please attempt to run your generator again.

I would also be careful and use a volatile air detector to make sure that if the generator works that it's not given off toxic fumes around it.

Thank you.

Gap the plug at .030 What is most likely the main problem is whatever gas sat in the carb. Even with fresh gas there will be some old gas still in the float bowl. You may be able to drain the bowl and be OK but I have a feeling that the carb will need to come off and be disassembled and cleaned properly. You can try spraying carb cleaner (I dislike starting fluid as it is too volatile and carb cleaner does just as well in this instance) into the carb/intake. Remove the air filter, open the choke, and spray the carb cleaner in through that way if possible. You can actually keep an engine running by spraying with short bursts. Even by just spraying once you should be able to get the engine to start. If it does start but then will not stay running without spraying more into the engine then it is a carb problem.

if you are running the engine at full CHOKE, then it is flooding the engine, but if you meant off full choke, then the carb is still stopped up. Try soaking in carb cleaner overnight after removing jet & all rubber goods. HOPE THIS HELPS.

take out the jets , and run small wire through all holes .should fix your problem

Changed plug since last year?Choke adjustment? try premium gas?

Fresh fuel? Does carburetor have adjustable jets? Turn the high speed jet (at bottom of float bowl) about 1/4 to1/2 CCW (looking at bottom of bowl). If no improvement, carburetor should be torn apart and cleaned. This also applies if there are no adjustable jets. Is there a fuel filter anywhere?

check this web site http://www.powermate.com/productmanuals.php?cat_id=3 you can down load the manual and parts list for your gen.

how old was the fuel in the tank and carb bowl? This could have built up varnish and make the float heavier
Another issue that my customers bring in are 4 stroke generators that have 2 stroke fuel put in tank.

A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems
