Hi, I recently posted how ethanol in the gasoline is destroying the rubber on the tip of the inlet needle valve. The additive is called fuel activator and is mfg in brooklyn,ny. It has a red label is 16 ounces, 1 ounce treats 20 gallons of fuel. I paid 16$ for
the bottle. I recommend everyone to use it, as it is an expensive hit to have this 30$ valve replaced and your carb and tank flushed and cleaned. It stabilizes and cleans the intake and exhaust, prevents sputtering and backfiring. The initial dose is double.
I would put a few capfuls in all your vehichles. It claims it doesnt hurt catalytic converters and fuel systems. I was thinking of running the carbs dry after everytime I use my quads, but the mechanic claims this causes other concerns and problems. No matter what it seems like you cant win, hope this info is useful to others, thanks rick
