Tech info wanted; Lean Burn Dist

My lean burn dist has only 1 pickup.

The lean burn system was the very first computer-controlled engine managment system Ma Mopar used, so they made constant changes to it in the enterest of improving it. So, some distributors only had only one pickup, while others had two. Some lean Burn distributors had mechanical advance mechanisms and a vacuum diaphragm, whike others had a locked-down plate and no diaphragm. Mine has two pickups a locked plate and no vacuum advance. It has the two ickups out-of-sync with each other, and they were used one-at-a-time; the "retarded" one was used for starting, and the other one was used for general running.

I want to use the more advanced pickup for stall-starting and off-the-line grunt, and switch over to the second pickup for the rest of the trip down the strip.

That sould give me 22-24 degrees of advance for stall-starting and switch back to 18 degrees, once underway (maybe 60-80 feet from the starting line.)

Anyway, it's just an experiment, but, that's the plan for now...
