RE: Question about gas to oil mixture........
One thing with a gasser is: DO NOT go rich of peak. set the high end for max rpm and keep it there. Gassers have a carb with a regulating pump. Kinda like using a perry pump on a glow engine. It will not go lean in flight. Going rich on the high end will only foul the plug and leave carbon deposits on the piston and ring. This will cause more problems down the road. The low end will affect the high end. On initial startup, set the high end so its close, and then work on low end. Once the low end is set, then the high end will need to be adjusted again. With a gasser, a little goes a long way.
Happy tuning,
