I thought they were called 3mm stroker cranks either way mine needs some work to run good. I thought about the idea of using a stihl ts400 cutoff saw cylinder. They are 49mm not sure if it would work. The mounting pattern is probably different. Got the idea from those 92cc engines robert was making.
So the mzmiami cylinder is for a 38mm stroke engine? How many extra gaskets would be needed for 38mm engine. I think I have one has the zae 50 rod it’s a spare engine, castings weren’t very good on it and they painted places they shouldn’t. I wanted to use my current engine because of the 8mm studs the other has 6mm.
