Terry, that was my reaction the first time I ran into it. It was on an RX-7 rotary with some sort of injector problem (never solved that issue). It wouldn't start, but literally had fuel fogging out of the tail pipe it was so rich. I put in new plugs and it barely started and ran for as long as I wanted, but then it wouldn't start after I shut it off. Changed plugs again, it would barely start and run, shut it off and it wouldn't start. One time it almost started, died and wouldn't start...changed to another set of new plugs and it started. After 4-5 rounds of that, I gave it back to the buddy and shrugged my shoulders. Not sure why, but I concluded that the over-rich condition just killed the plugs.

Glad you got it fixed.
