They were a very popular engine on the racing Karts back in the earlier 70's. The racers were direct drive, no centrifugal clutch because they didn't make a clutch back then to handle the high RPM's of those engines for Go-Kart usage.
They did make a Go-Kart scary fast back then when you put a big chainsaw motor on it. Better have good brakes on the Kart to slow it down when you had the 2-Stroke Chainsaw engine on it, or you aren't going to stop it in time.
