Here are some links, both pro and con comments. Take a look. I plan to convert a COMO .90 and an ASP 91 and 1.08 to gasoline with a CDI and 1/4-32 spark plug. I am not looking for max performance and will use plenty of oil and NOT replace my connecting rod bushings for bearings. I need to source an adapter for converting the carb adapter to fit a Walbro to the engine. I will use an RCEXL CDI. Good luck on yours. Where in VA are you? PM me if you wish.

Sincerely,
