Me too. Sort of. It's a common failure. What I've found is that if the isc or fidle fails, the other two idle adjustments get messed with/up instead of finding and fixing the real problem.

MB, I've never seen that adjustment before. Dave took one apart, but I don't think he ever managed to get pics posted on it. I assume it just closes up the fidle when the wax pellet fails.
