Thanks, RC. From your current and previous posts, I gather I can take (for example) a Ryobi 31cc, remove the flywheel, magneto & spark plug, make a glow plug from a spark plug or buy an adapter, buy a WT-499 glow carb from Zenoah, buy or make a prop hub and muffler, and use 0-5% glow. I should end up with a weight of around 2 lbs., which is the purpose of the exercise. Am I oversimplifying it, or leaving something major out?
