Re: spak plug head comes loose
The main thing that matters with the plug is that it doesn't extend too far into the engine. You don't want the piston smacking into the bottom of the plug. Bad things can happen then.
Any day that starts with a good ride is already a better day, and a bad day riding still beats a good day working.
