i recently purchased a bt-43ei and installed it on my airplane.
when i got it running,noticed the airplane shaking violently.
got to looking and found the rotor?,the part that spins in front of the hall effect sensor,was wobbling causing the prop hub and prop to wobble when the engine rotated.

was wondering if anyone else has had this problem,and how the warranty would be done to replace this part(I would rather not send engine back since it has had fuel in it)?

thanks,
Kevin
