Looking for a gas engine in the 23-28 cc range that is very narrow, hopefully to fit as completely within a 1/4 scaleCub cowl as possible, don't mind the cylinder protruding from the bottom so much, but want to avoid big gashes in the side for carb and /or exhaust. I have a US -41 for a different plane, something along those lines, maybe with an angled carb. Anything like that out there?
