This is probably why ive been having such issues with mowers lately too. Ill have to keep this one in mind. I had a 6hp honda engine stop running on me due to carb issues and i saw the same buildup. although for me i just gave up and bought a new one..

This is absurd. I cleaned the carbs on my bike a while back. Ran 2 tanks of gas through it(with fuel stabilizer), and it was running fine. It sits for a month, and then wont start. Pulled the carbs again today, and the idle passages are partially clogged yet again.



Im thinking it doesnt affect fuel injected engines because the gas never collects in places where it can evaporate, unlike carburetors. Pure gas evaporates cleanly, but ethanol leaves deposits. So all the ethanol the gas companies are putting into modern gas is wrecking havoc on carbs, and it looks like the winter blends are even worse.



Maybe I should just start running 100LL in my bike...

Deposits hell that **** is hard a rock it leaves concrete lol



Well I think we can safely say a month is too long and I've found no fuel additives that keep it from forming. The gas still evaporates leaving the **** ethanol " deposits" behind.



Here's a list of ethanol free stations http://pure-gas.org/



With any luck there's one in yer area.

Luckily there's a station a couple miles from my house.



I have gas cans for kerosene, 2 cycle, regular gas, I guess I need another one for "pure gas".
