Hello all, just a quicky. I think my owb is slipping as the pull starter does not turn the engine over at all, no resistance. It was running fine before this happened and now obviosly i cannot start it. I havn't checked the owb yet as i am new to nitro and thought i would ask here first, a quick read showed this part is not available as a spare and if its knackered can anyone point me to a compatible all metal part that would fit or if cleaning the bearing would solve the problem, thanks JeffyB
