come on guys, plenty of you have had to get moisture in your pull start assembly and then find the one way bearing not working properly. Somebody has had to find an oil that protected without gumming up the system. Thats one fualt I have with OS engines that some of the others have a little better setup I think. OS pull starts have the oneway sort of external, its in the little unsealed plastic box the rope winds into. Other engines I have seen have the oneway behind the backplate, basically inside the engine getting the same lubrication as the piston, rod, and other bearings.
