Bigger studs on my second engine.
I bought a second China engine and posted a thread about a hole in the "jug".. I was going to try to remove the stud before using JB weld for repair. When I removed the acorn head nut i noticed that the stud on this engine is much thicker that the 66 cc I got. This one is supposedly a 80cc, but I suspect it's really a 66cc... anyone else notice larger studs on one engine from another?....
