AHHHH BEER!

 

How does the threads look?
Did you forget to tighten the plug last time you had it out?
...........Caper.........

 

i assume the threads were fine due to the fact it went back in and tightened up fine..and YES IT WAS ME, i replaced the plug at my 2000 mile FULL SERVICE and it now has 2168 on it!!!i do a full service every 500 miles or 100 on my fluids if i been past the low beams in water or muck!

 

oops savage lol . the main thing it didnt hurt anything and alls well.

 

I can't believe that as the plug was spining itself out, got to be about 10-15 turns, that it didn't loose compression when the plug seal was broken. Glad to hear it wasn;t anything major.

 

it never even stumbled or even sounded weird until it shot out and the NOTHING!!! least i figured it out and did not have to get pulled home...

 

Good work on the trail to keep her going. I have had to be pulled home 2 times with my polaris and pulled one home myself. Never have a real good feeling about that.

 

I had a 1993 Isuzu Trooper that had a problem with spitting out spark plugs. It would leave the threaded end in the block but spit out the insulator. What a racket. Defective plugs was the problem. I think I'll go check my plugs....
