I'm not sure but it might have something to do with not starting it for two years .I'll get it, it's too damned cold to work on it right now .I didn't know ethanol could gel up and clog a carb
Ethanol can freeze like water, but at a way lower temp. It isn't the issue with our climats. A major problem comes with the moisture took by the ethanol from the surrounding air. It then reacts with the instable products contained in the gas and forms some corrosive agents (amongs other craps like solvents and gums). What can clog the carb is the wrecking of the carb's aluminum body by this corrosion. The salts/oxydes of aluminum take a lot more volume than the virgin metal. That gives a little pitting on the surfaces, no worry in itself, but a big glob of semi translucent stuff protrudes over it, obstructing easily the small drilled holes.I didn't know ethanol could gel up and clog a carb
Nothing like opening up a carb and finding those little balls of jelly.Marc nailed it 100%.
I almost ruined an unreplacable atv carb by leaving etanol lace fuel in it.
