this should be in troubleshooting section, but you should open both covers and see where movement stops

Hi you probably need to adjust your clutch.
Take off the right side cover and tighten up the flower nut

either clutch too tight! loosen clutch nut(. not tighten, or internal problem?
main drive broke. probably the clutch, they are extremly sensitive on the "girl"

so after a few hours of reading through the forums im curious if the clutch shaft is the same size for the 48cc and the 66cc need to adjust the spring a little or just swap them out while im rebuilding the 48cc?

If I'm not mistaken the whole bottom ends are identical. And I must dispute the above claim that the ChinaGirl clutches are sensitive. They are finicky, and can be difficult to adjust, but once you get it tuned in, hammer on that sucker for a few thousand miles, you'll kill the rings or something else long before the clutch, IME. I'll leave a real tip another time.

woodruff keys are usually different - swap all as a unit
