It's almost impossible to rebuild an engine without stripping a thread. Here is how I fixed mine.

I use the Recoil kit.

Here is the stripped thread.

I masked off the the area. Don't want any metal flakes in the engine. The tape on the drill bit is to know how deep to drill.

Then I use the tap in the kit.

Then I put the thread coil on the tool.

Then I screw in the new thread coil. It's important that the end of the thread coil is screwed about 1/2 to 1 turn into the thread to grip correctly. In critical applications I use a small amount of Loctite thread lock to be sure the coil stays in place.

Finally I hit the litte tab and pull it out with a long nosed plier.

There you go. A new thread that is stronger than the old one.
