Unless you have an engine with a different piston/liner than it’s supposed to have, you don’t go by what is stamped on the piston. You work with measurements. The published information on these three engines (that are ALL made by GoldenLion/SH Engines) is posted above. Not arguing, just stating the facts. Measure your piston and get a button to fit that bore.
Ok, I understand thanks. I just threw away a lot of money on these 2 engines that I dont want to throw away much more. It was my ignorance that brought me to this point. I appreciate all the knowledge that you have shared.
