Re: Saito gas conversion - carb experience?

You can have some success with the stock carb but glow carbs have no fuel regulator so it would be best to use a cline system . A 22cc string trimmer carb would work best but you would have to make a manifold . .a engine running glow fuel uses twice the fuel of a gas engine so the glow carb is not correctly designed to meter the fuel @ 14:1 throughout the RPM range . Gas engine run 14:1 glow engines run 7:1 . Even if you get the low speed and the high speed set correctly the transition would be wrong because the slot in the main jet tube will be profiled for a higher fuel flow .. hope this helps ..
