Default How to fix the stripped plug threads on cyl head.

Need any suggestions. Marvin

I tried to buy a cyl head from ouir local hobby shop but no Thunder Tiger dealers could be found.
I'll contact time sert next week and find out the repair cost of a insert. Sounds interesting.
If repairs can't be done resonably, I'll just use the Thunder Tiger 60 for parts as it is an older but good engine.
Thanks for all the suggestions. Marvin

If it is glow, send it to Clarence Lee for a helical.

I have been using time-serts for decades for all types of thread repairs . The kits are pricey but can't be beat (way better than a helicoil)

Clarence Lee's repair service has been around for decades and is cheaper than buying the tools to do the repair yourself. There are probably thousands of engines out there that he's fixed, all working perfectly.

A Timesert is still the best. A plug can be pressed in and drilled and tapped too, but could loosen up if torqued. The 4 stroke heads can be pricey, and Clarence may be a good idea if you don't do it often. (and yu shouldn't need to)
