it just hooks to itself, wraps around the outside of the shoes, possibly lower your idle or check your oneway bearing

What kind of motor are you running? How long have you been running it (gallons etc.)? Check that LSN (low speed needle) and make sure it's adjusted to get the motor to idle.

Well generally, motors will need tuning. But since you mentioned you crashed a couple of times...your servo horn may have come loose, the broached portion is worn out, or something happened to cause the the throttle to open wide enough to get the motor's rpm high enough to engage the clutch.

Look in the engine forum here and then check out the Tuning bible.

if it accelerated a bit and then died, too lean low speed I think
you need to retune your carb, the needle might accidentally loose when you crashed
