Old ST 60 assembly
Engine is an ST 60 Italian made circa 1970's. took it apart some time ago to inspect and replace parts and forgot some details. The head has a tapered squish chamber with a slot at the deepest part of the chamber. There is an offset tab machined across the top of the piston that mates into the slot of the squish chamber. I thought I remember the piston assembled in the engine with the offset tab closer to the exhaust port. Is this correct or should the offset tab and head slot be closest to the transfer port?

RE: Old ST 60 assembly
please disregard, i assembled as instructed on another forum and had problems tuning. Found out the assembly was correct but I didn't have the spray bar in the carb aligned properly...running good now.
