RE: McCulloch 31cc w/ Rear Exaust and Carb, is it better?
Looks like the fins on the flywheel could be cut back. Less weight and less air grab. Also engine box could be drilled out with a partern of small holes...again loosing weight. Then put a ignition like RCIGN1 has. Save more weight...no big flywheel. If that is not lite enough... go to glow/gas mix. Good Luck, Capt,n
