Fixed my stripped out plug hole on a 22 hp Kohler lawnmower engine. Easy to use very pleased with the fix mower is working fine. Replacement head was over $100.00 . This was a cheap fix.

The bit worked well, the inserts were a couple thou undersize. But with enough thread sealer it worked out.

Not worth the money made out of a weak metal. Can't use them,when they instantly strip out!

This Camrusic spark plug thread repair kit is something you should hope to never need but will be happy you have it should the need arise. We were recently working on an old generator and the spark plug removal was suddenly a huge issue. We can only guess that the spark plug was installed incorrectly when services a couple of years previous but however it happened the spark plug threads were ruined. We ordered this kit to allow us to cut new threads and install the thread inserts to allow connection of a new spark plug. The included tap worked well for our need, but I caution anyone doing this to take your time, you do not want something to go wrong while you are already attempting to correct a major issue. The inserts are of high quality.
