Hello,
I disassembled my Sirio 12 engine to replace piston/liner. However, I forget to note down the orientation of the conrod. I notice that the conrod, on the end that is to go to the crankshaft, have one side with a small oil hole with a long groove, and another side with just a short groove and no hole. Should the "hole side" face the conrod, or it should face the backplate?
the small oil hole should be facing the front of the engine.
