Make SURE if you decide to try to fix it that you get a carb kit that's ethanol friendly and fuel hoses that are ethanol friendly. Or any work you do on it will be for nothing.
I have a weed eater that's not to old. When I went to start it couple of weeks ago, it would start and barely run, any throttle and bleh, quit. When I let it sit and primed it again, the bulb would not come back up. Well, I found out the fuel line had dissolved from the alcohol, and o=plugged the return to the fuel tank, more like a pressurized line, and the fuel line itself was crap. Cleaned it and the new line, thing runs like brand new.Like to take a trip out west of here to get the good gas with no alcohol in it.
