I would like to repair the spark plug threads on my Poulon chain saw. The metal looks like aluminum but aluminum rod will not stick.
I tried JB Weld, and another type of liquid metal, and these both did not work.
i cannot find a heli -coil that will accept spark plug threads....perhaps I have not find the correct one?
But welding the hole smaller then drilling and using the spark plug tap / thread chaser i have I think would be better...but i have not found a rod that will stick..what shall i use or what other methods have you found to work well?
