Briggs and Stratton 31P77 0299 E1
My sears LT2000 was running fine UNTIL I started using gasoline with methanol (10%) for the fuel. It appears the ethanol corroded the fuel system parts that were metal or rubber or the tip of the gasoline shut off solenoid was completely eaten away.. Now the engine will start right away then speed-up then almost stop then repeat this cycle until the smoke is so bad I have to leave. Sorry, I got ahead of myself, the engine really smokes a lot and the exhaust throws out oil that completely empties the oil reservoir in a few minutes. The engine will never settle down to either an idle or full throttle. I have replaced the 'gasoline shut off solenoid" under the float bowl and that helps with the cylinder being completely filled with gasoline. Have to take out spark plug and turn engine over to get gas out of cylinder. I adjusted the needle value to from a snug seat to 1.5 turns open, but then it won't start so I open it to 4 turns.
PLEASE, what's my next action? I use it for mowing and pulling a small Sears cart around 5 acres.
