Go to pull the starter rope and about pulled my arm out of my shoulder. Said WTF. Checked oil and was overfull and smelled of gas.
Keep the fuel shutoff when not using and it solves the problem. I also found a local station that sells non ethanol fuel. Ive been using that this year.
Not an engine problem but a fuel problem.
Honestly? If you get diarreah from eating Mexican the night before, do you blame ethanol too?
