I just put one of the thumpertalk decompression plug, I was just curious, when i put mine in it was a little loose in there, but i had not started it or anything yet, when I did start it I had no oil leaks of anyting coming from there! Just want to hear if anyone else is running them!

 

anyone

 

I've got one in mine. It was pretty tight going in though.
No leaks to date, and I put it in last June.
I believe I also got it from Thumpertalk.
