That cap needs to be changed! Looks like the rotor was hitting the contacts? Is there excessive side movement in the distributor shaft? There could have been irratic spark flying around the inside of the cap causing a misfire condition. I don't like black caps cause it is hard to see carbon build-up that also causes spark to jump around.

Just Sayn'

Yes it is obvious that the cap needs to be changed! No there is no side movement in the shaft. With guys having problems with rotor phasing and it being up to 30-40* off from the correct pin inside the cap, there very well could be spark jump going on inside the cap causing fireworks to go off and miss like all get out, I don't put it past it one bit, I should have drilled a 5/8 hole in the cap to see WTF was going on in there. The Tuner is blaming all this on the Computer and is telling me to just buy a Haltec?? Throwing Cubic Dollars at a problem is not the way to fix anything. Not going down that road until I find the issue. It could be something small like this causing a world of head aches.

I talked to someone that was there when it was on the Dyno and they said........

it started out good with no misses when it was first running Brian hit the throttle a few times and it clearly was not missing at all, the more the tuner fd' with it the worse the problem got..........

I am not saying that it was his fault, if the cap was getting progressively worse or the Slop in the Dizzy started up, it could be that also.

To me that Fast Dual Sync with that slop and the other issues with phasing and spark jump, is a Piece of chitttt.
