Hey,

I somehow managed to burr the spark plug threads on one cylinder last night.
All the tin on these air cooled motors makes changing the plugs much harder
than it should be.  Very frustrating.  So I am going to have to find a tap
to clean them up.  I didn't force the plug in at all, once it started
catching on the top thread I backed off immediately so I think the damage is
pretty minimal.  So any words of wisdom on cleaning up the threads?  I
believe Sears carries a tap made just for this.  Are spark plug threads
pretty much universal?

Thanks, Jake
