This little powerhouse is smaller and lighter then other Zenoah PUM engines, but even in stock form , puts out about as much power as a 231 PUM.  It can use mounts made for a standard Zenoah PUM with easy modification, and the exhaust port bolt spacing and size is the same as standard Zenoah. It is supplied as shown with carb, velocity stack, ignition box and recoil.    We have these in limited supply with full availability expected in early spring.
