Merry Labor Day fellows,

On Aug 13 I posted about a no run problem that really had me scratching my head. MANY thanks to each of you who thought through the problem and offered a suggestion. We knew it was spark and most of us were thinking coil or float. I had my Holley so well tuned I didn't want to tear into it but did check gas level in the float bowls by opening sight windows and all was well.

Since I had wired every wire in the vehicle the long weekend was a perfect time to trace voltage in every wire and connection. And of course they were all good.

That left only the dizzy, cap and new Accel wires. As DI says, we need a lottery! Well, Reed won the lottery! Even though he PM'd me I want to share his suggestion which was very close to what happened. Reed said"

"My next suspect would be the plastic distributor gear. I have had these crack or chip a few teeth away so that the distributor would still turn, but it would slowly get out of time, then back into time with the motor. The car would run fine, then loose power, then die, rank-crank-crank-crank-crank, catch, run badly, slowly get better, run fine, then die, etc... "

Sounds like my problem doesn't it? Upon pullng the dizzy the problem was found. Not the gear, rather it related to recurving. The little clip that holds the governor on the shaft was loose. I hadn't got it completely snapped around the shaft. When I pulled the rotor in the dark to look at the rotor, that let the governor pull up slightly and that caused the weights to come out of the governor! Amazing to me it would start and keep running enough to get me home, but that is a slant for you. Moral is, recurvers, beware of that clip! Probably some of you, as I, have even made a decision to run with out the clip and had no problems. It caught up with me this time!

And in the process I found an intermittent connection inside the hot wire to the coil from Ignition switch. A new, snap together connector at that. It seems the Chinese made one that didn't have the little brass male connector tab well attached to the wire in the connector body. I am convinced now that is why I believed I had a bad Blaster 2 a while back in a post of a similar slowly dying problem. When I put on another coil my actions eliminated the intermittent....for a while.

So you put together an intermittent in a new connector, and the wierd dissy problem, you have a hard to diagnose problem in the dark. It only took 5 hours in daylight to trace it out.

Glad to hear you found the problem. Intermittent electrical problems can be a biotch to find. :?
