Not sure if I initially wrote it correctly but yes the Nate one way bearing does work well. It requires some omnipresent belt tension so The belt actually will spin the crank. Also if the bike sits for a while the minute oil on between the bore and the rings probably dissapates making it hard to spin the engine. Two ways to deal with that
1 back out plug and spin for a bit with pedalling. Make sure if u have the plug out the kill switch is on so as to not fry your CDI.
2 haven't tried this seeing I have a cover over the magneto but spinning that by hand a bit should also work.
