Hrmph.  Mine does nothing.  Looks like I found the problem. :)  I'll check 
it out tonight.  Any idea how much those switches are and where I can get 
one-- assuming Potterman or Mark?

Just curious.  The one thing that I found strange is that in the past, when 
I tripped the idle microswitch, idle jumped to like 1100rpm from its normal 
900.  The last time I tried it, it dropped from 900 to like 750.  Strange-- 
but could be that the engine was warm, when I usually do it when it's cold.

I'ma check out the cap/rotor tonight-- though my feeling is that it's OK 
because the car's fine under low-rpm high-load (when ignition problems 
usually rear their head).  The wires are about 2 years old, so there should 
be no prob there.

For lack of a better phrase, HELL FUCK YEAH! :)  I can't wait!  Daun's 
place is usually the best meet of the year, so it's something I wouldn't miss!

Thanks for the response, Brett, and I'll test that MicroSwitch tonight.

tty'all later,
Jason
