Are you using the washer for the gluw plug? If you don't, install a washer for it. Tight the glow plug when the engine is cool that way you can adjust a little tighter without strip the cylinder head bottom. Try this and replay back with results. GL

That is odd! You sould have something that vibrate a lot when runing to make that plug comes out. Did you remove any washers from the cylinder head?

The thread in your Head Button is probably stripped or damaged

Hey trice0683,

You wouldn't happen to be using an OS-8 plug or similar "short" plug, would you?
