I can see a mark on the flywheel and when it lines up with a ridge on the case - that's top dead center . If you have the spark plug out - hooked to the coil - grounded - key on - rotate the fly counter clockwise will you see a spark jump the gap when you pas TDC. ???? If you can I'm thinking coil or cdi. So when a cdi goes is all or still some spark ? I have done everythin BMX has done and I'm at the same spot !

Get the proper tool to remove the flywheel, or else you will most likely damage the stator or the crank.

Definitely NOT a starter issue,

Key was intact. I ordered a new CDI.

why would a bent flywheel key make it stumble like that?

And why would having the kill switch on or off make a difference?

This is a two stroke , so valves are not opening or closing.

why would this not be a starter issue?

A bad ground to the starter would make it stumble

The kill switch being on could be making a better path to ground.

Because it is so lean or rich that it is 4 stroking, is why.

There is no way this is a starter issue.

A bad ground to the starter would make it stumble No, electricity does not work that way.

The kill switch being on could be making a better path to ground. The kill switch goes only to the CDI and is totally separate from the starting circuit.

One day I started it -it backfired and quit ! Kicked it again and started right up , put it in gear let the clutch out and what the *, I'm going BACKWARDS !!! What happened is when it backfired it sheared the key and the fly moved on the crank ! By the way 2-strokes run as good backwards as frontwards . Thats the way old boat motors had reverse > you would shut the motor off move a lever changing the timing start it back up and you were in reverse !
