noisy engine
I have a OS 46 LA engine in one of my trainers and I noticed a knocking noise coming from it whenever I'm below 1/2 throttle. I asked someone at the field about it and he said the bushing was worn. I checked the OS site but I don't see a listing for the bushing. Does it come with the crank?? Is it the thrust washer?? Any help would be helpful[8D]
