    I had a lawnmower with 4.5HP Tecumseh flathead engine. The spark plug thread was badly stripped thanks to the soft aluminum material. Bought this kit and got it within 3 days. At first I thought that the cutting tool will bottom out so I took off the head. The graphite gasket was falling apart but I managed to reuse it. Upon closer inspection I realized that I didn't even need to take off the head, the cutting tool barely need to get in all the way to cut the thread. So folks with flathead engine might consider tapping without removing the head to avoid troubles with the head gasket.

    Now the lawnmower is working fine and the thread is much stronger since it has a steel insert.
