Six Pack issues and rebuilding by tommyg29

The car is running much better, but not quite perfect yet.

I replaced the alternator, but the VR wont screw tightly to the firewall. I think the posts may be stripped, as the screws wont fully tighten. I filed the firewall area at point of contact, and put a couple star washers in there to help bite, so I guess Ill try another trick (stuff a small copper wire in the screw hole).

If the VR doesnt have a good ground contact wont that only cause an overcharging condition? My problem seems to be undercharging. At idle yesterday it was reading 12.4 volts and holding steady even at higher rpms. Then restarting it it read 12.38 at all engine speeds. Then restarted a little while later and it read 12.34.

The new alternator tested good in the auto store, and when I put my battery on the battery tender it charges up to about 13.4 and holds there.

Any more on this and I'll post questions to an electrical thread.

I did the test from the battery posts to the alternator case and the output post and it reads ok.

I will test the coil tomorrow.

As far as the carbs, I think I am done with Phase 1:

It seems to be idling well now   

Now, on to the next step, which I think may have to do with the secondaries, only because I havent done much adjusting with them. Basically, its the jetting, idle screws, float level, mechanical links on the left and vacuum action on the right. Not much else I can do. Anyways, I installed 80 jets front and rear as a start hoping they would be close.

Whats happening still is I am getting dieseling, which I thought couldnt happen with a MSD6AL system, but  

Then, sometimes, especially trying to restart the engine just moments after shutting it down after running it a few minutes, it will cough and spit backwards a huge puff of brownish smoke back through the air filter. Tonight it spit what looked like a raincloud into my garage.
