Missing in action - resolved!!!

[Robert Myers]

I was clutching at straws.  Ed Kellock tossed me yet another straw.  Try 
swapping the plug cigars.  Well, it was brand new but what the heck.  So I 
swapped cigar #1 for cigar #4.  Reinstalled the coil pack loosely.  I just 
screwed one of the four Allen head bolts (#2) which holds it down loosely 
in place with only mild hand supplied compression of the springs.  Fired 
the engine up and - BEHOLD!!! - no miss!  OK, why a miss when it was at #4 
and not with it at #1?  Iss a puzzlement.  OK, let's fasten it down 
properly.  Left the engine running and put in screw #4 and tightened it 
some and then went back to #2 to tighten it some more.  Then back to #4 for 
some more tightening.  Suddenly it started missing again.  Hmmmm...  Backed 
off of #4 a bit and the miss went away.  Tightened it a bit and it came 
back.  Loosened it again and the miss went away again.  It was consistent>

OK - I have a clue.  Tightening those bolts puts some squeeze on the 
wiring.  Something is either coming separated or is being forced together 
while tightening the bolt.  It's time for some more extremely close and 
careful checking of the recently redone wiring harness.

Pulled the coil pack once again and examined the wiring harness where it 
passes through the little clamp designed to hold the wiring in place.  Aha, 
the wires for #4 cylinder are being compressed very tightly one against the 
other.  Took the clamp off and looked closely there appears to be an almost 
microscopic spot where the insulation (shrink wrap) has been cut through by 
heat and pressure leaving the wires in contact with each other. and 
shorting out (by-passing) the #4 primary windings.  I fixed the situation 
and reinstalled the coil pack once again, this time with all the screws 
fully tightened.  The miss is gone!  (Yippee!!!)   Now the question 
remains, "For how long?"  It looks like perhaps shrink wrap is not the best 
insulation to used under the conditions experienced in this location.

Can someone recommend a better insulating material to use for this 
job?  Preferably one which is fairly readily available.  I don't mind 
redoing the job once again provided it meets with fairly permanent success.
