Right Mk23socom, I wasn't saying it can't be done or can't work. I was saying it's not practical as a DIY project, especially for a beginner. The power output will be lower with gas, the weight will be higher, and no matter how well it's done, a conversion is a adaptation of a design to do what it wasn't designed to do. Add to that the expense and time invested, and it's tough to make a case for gas on these smaller engines.
