Stripped spark plug threads in lawn mower..

Well I guess itís my turn for some bad luck. I replaced the spark plug in my lawn mower and apparently I tightened it too much and stripped the threads in the aluminum head. What is the best method of repair? Is it possible to get a little larger plug and rethread or will a helicoil work? This is a 2-cycle engine so the cylinder is part of the head.

Thanks in advance

Any way you do it, the head (jug) will need to be removed, so I would reccomend just replacing it. I believe there are helicoils made for this application but I've never used one for a spark plug.

If the spark plug is a tapered seat then you'll have to replace the jug as there is no thread repair kit for these. If it is a standard, gasket type spark plug then you do have the option to repair the threads. I prefer Recoil brand versus Helicoil brand.
