Well it's time to get back into the conversion thing here! I'm looking for a front carb, rear exhaust engine (side exhaust is ok) around the 20cc range. Does anyone know what units are out there? I have been looking for a while with no luck. I have a GP Tigermoth just begging for a little gasser! My Maloney's are to wide at the carb and I don't want to butcher the cowl (just bought a new one to replace a butchered one from the previous owner).
