To answer you briefly, I generally just don't recemmend it. I do have a Super Tiger .90 that I converted to gasoline and ignition and I enjoy it. However, I converted it to a Walbro gasoline carb, converted the crankshaft and connecting rod to roller bearings, and I watch the heat factor like a hawk. This is a quite expensive proposition unless you can do all the machining yourself, and really, for what reason?

All in all, better to buy a factory designed and built gasoline engine. If one is stuck on the idea, I suggest converting to ignition and methanol instead of gas, and using the original oil ratio for the engine. This to me, is a more logical/feasible idea, and how I personally am doing my next conversion of a glow engine. Methanol can be purchased at auto or go kart speed shops or race tracks for around 4 bucks a gallon. With Methanol, your glow carb will work fine, though if you want the advantage of a Walbro carb, a WT-499 Walbro is calibrated for Methanol, and is suitable for 20 to 30cc engines. (An engine uses double the Methanol than it would gasoline, hence the need for properly calibrated carbs. Glow carbs generally don't work well using gasoline for this reason.)
