What is the best way to repair spark plug threads.
I pulled a spark plug from my rotax head and noticed part of the threads from the head was still on the plug.
I always use anti seize on the threads and torque them but part of the thread in the head is gone.
Was thinking of a heli coil to repair it.
Not sure how well they work or if there is a better way.
