SPARK PLUG CROSS THREAD

Oh, I was hoping you could get more specific than "old-style".  Have you recently replaced the plugs?

All fixed. Only first thread or two were buggered. This is a great tool. All debris is pulled out of the cylinder instead of being pushed in.

I was in the process of replacing plugs NKG DCPR8E  during my annual. 

Glad you got it fixed.  What did you use for the heat-conducting paste?  I have the stuff from MG Chem that Lockwood sells, but I recently saw the video guy here on Rotax-owner recommending something else.
