I mean the lever on the motor itself, not the hand lever. I'm just curious. I'm trying to feed my chain into the drive gear and I can't disengage the drive gear. It seems like there is a little metal piece in the middle of the drive gear, and that the intent is that the clutch lever will push this in and disengage the gear. However, I can't push it in. Should I be able to push this in by hand? I found this video randomly as well. YouTube - bicycle engine kit clutch checklist When I open up this I can't unscrew the "locking nut". Is there something locked up in my clutch assembly, or is there something that I am missing?
