I just recently got a riding lawnmower and discovered that the spark plug hole is stripped out so the plug wont seal. Its a regular 1 cylinder, gasoline engine. Would the local machine shop be able to fix this? Or is there someting simple I can do to fix this? I tried rethreading the hole and the threads just broke off leaving a smooth hole. Any help or suggestions would be great, thanks!

your local machine shop should be able to install a heli-coil for you. It would be helpful to your shop if you remove the head and just bring it to them. That way you don't get any metal filings in the cyl. I've done quite a few, takes about 15min. depending on the mood your machinist is in. grin

You may be able to get a new head for cheaper than getting it fixed, especially if it is a flathead Briggs engine. Check with Roy Boy's (near Washington Square), they have a good stock of parts.

Yeah, I was told that I could buy a helicoil kit, I might try that and see how it works, if it doesnt and all else fails I will try to search for another head. The wierd thing about this rig is that it has a generator that acts as a starter and turns the motor over, and then has a coil out of a truck, has anyone ever seen anything like this? I wonder if someone added this all on, if not then I will remount everything so its hidden.

Thanks for the help all, I will try to get pics of this thing sometime and maybe show everyone!

If you can find a larger plug that will work, then just bore out the plug hole and re-tap the threads.

I had to replace a head on a lawn tractor once. Head and gasket cost me $12. I doubt a helicoil kit will be that cheap.

You should take the head off to put the helicoil in (drill shavings) so why not replace the head.

good luck either way!
