Found a newer style vertical shaft in the dumpster at work. I was curious to see what had changed since the 70's when I was a kid fixing mowers. There is a lot more plastic, the cam gear, oil pump housing, and a plastic bushing on one end of the cam. Also a real centrifugal compression release.
I popped the head and the combustion chamber is completely different. Does anyone know if this newer one makes more power, sure looks like it would flow better. Wondering if it could be installed on an older tec?
