Helping a friend. Generator with B&S engine sat for about 3 years with gasoline in the tank. We got it started, but it ran only briefly (w/ lots of manual overide on the throttle contol lever), then it died. From trying to re-start, wound up with fuel leaking out of carb. Stopped working on it for a few days.
Somebody then took out the fuel.
Later, I took apart the carb (and wound up with a handful of parts and no diagram). Sure enough, lots of yellow gunk in the bowl and around some of the parts. I cleaned out the gunk, reassembled it (no parts left over). Put in new fuel and some Stabil. (And replaced the slightly fouled spark plug.) Still won’t start.
I’m thinking that one of the fuel tubes or the jet is still gunked up. Is there any solvent I can soak them in to try to clean them?
(Man at the service/parts store said usually have to replace the carb, but for $100, I’m willing to try a little harder to clean it out.)
