1) Get into the habit of turning off the fuel cutoff valve and letting the carb run out of fuel. NO GAS REMAINING IN THE CARB at the end of the day means nothing from which to form gunk if you leave it in there for too long.
2) Try to use fuel stabilizer each time you purchase gas.
3) Attempt to purchase straight gasoline, rather than ethanol-gas. Ethanol attracts water from humidity in the air and ends up condensing in your gas tank.
a) Gasoline and Water will not mix. Water will puddle in the gas container.
b) Gasoline and Alcohol will mix. No puddle.
c) "Water and Alcohol" mix too. No puddle.
ONCE THEY HAVE MIXED;
d) Gasoline will mix with "Water and Alcohol" , resulting in:
UNSEEN WATER MIXED IN YOUR GAS!
I doubt if any engine is designed for this mix (d), so don't give it to your engine.
