RE: Does conversion roughen an engine?
RCIGN1...maybe I am reading your post wrong but at first you say there is "NO" rpm increase in a glow conversation then in the last sentence you say there is a 600 rom increase and a G26 turning an 18/6 @8000...that's more than a G38 on gas.
I must have missed something...anyway...can you help me find a carb for a 3.5 BME(real old) or a carb for a G62.
