Any ignition guru's out there

While at Byron a couple of weeks ago the ol wagon was doing a pop-pop at the hit of the throttle, and then some mild missing at the top end. We tried THREE carbs, worked on the jetting each time, to no avail.

The folks at MSD said something about RF noise.

Purchased a shielded cable, redid the trounds, removed and replaced the multitude of connections from the changing of components over the years. Put it all back as per the MSD Tech Book (actually, the way it was but cleaner). Fired it up and it chugs and quits like it's out of phase. HMMMM. Took a spare main lead and changed the phasing. Oddly enough it ran the same. WHAT'S GONG ON HERE. Two slow records in IHRA is one thing, but a car that won't start is a real problem.

OH, a new coil too....

Is the MSD bad? I disconnected the tach and all perriferals and wired it as a straight MSD with the same results.

I need serious help - I'm no electrician.

Peace, Rev. Mopar you can Email me at Racewthrev@aol.com
