I have a 96 300 4x4 and it wasn't firing when I first got it so I had the plug in and out while trying to find out what was wrong. There was no oil on the plug until i got it to fire. Now it's soaked and not starting. It turns over and then tries to start then turns over then tries to start. You could set your watch by when it's gonna try to start. It also backfires through the carb. So I checked and it's in time. The chain tensioner is all the way extended so I know I need to put a new chain on. Question is would this cause my symptoms or could it be rings. Don't understand why the plug only got oily when I got it firing.
