O.S. 61 SF-H I have this engine that I bought used, it's the helicopter version with the black head. It needs a new piston and ring. I bought what I thought were the right parts, 27703200 piston and 27703400 ring but they are not correct. The 27703200 piston is .900" and the piston in the engine is .940", didn't measure the rings but laying one over the other it's clear they're not the same. SO - anyone know what the correct piston and ring are?? |
