Cool! I didn't know if it'd push through I have drive sprocket off , had just managed to cut some thread using the puller haha only about 2 threads so didn't want to try pull it.
anyway i got everything apart , reason was the edge of the crankwheel was extremely jagged like it was grinding on something took whole thing apart but found nothing musta just been the way the crankwheels were installed but the other is considerably smoother (altho not as smooth as other engines)
