I recently split my 8N (front mtg distributor) and replaced the clutch and transmission oil seal. Put it back together and all is good. I had removed the hood/gas tank to make hoisting front end easier so I decided to change spark plugs. Number 2 was rusted and being in a hurry (that always seems to bring tiding of bad news) I broke it. I tried an EZ out to no avail (square fluted one). I even heated it (I only have MAPP gas) to no avail. So as a last resort I drilled it out with a drill bit that was close to the major diameter of the plug hole. I was doing this without removing the head so I used a hand held drill. I re-tapped it and somehow I managed to ruin several threads. The result is the plug is loose for the first few threads and finally locks in on the last 1 or 2 threads. I had to not use the spark plug metal gasket to accomplish this. I ran the tractor for about 10 minutes and the plug did not blow out. What should I do now? Leave it alone? Use Locktite on this plug ( I hate this)? Go the helicoil route? Any suggestions would be appreciated. By the way I did clean out the cavity using a small magnet prior to running.
