Hey guys, I know I've been posting alot of questions, but I'm not used to chryslers.. Anyway, it says in the car, that I should have my timing set at 12* BTDC, is this with the vacuum advance unplugged, or no?

You must disconnect and plug the vacuum line to set timing. You should also make sure the idle speed is set properly first as well. Some things to watch for:
1) The stock 12º timing may not work well with the conversion kit. It may want 10º or less.
2) Vacuum advance may be adjustable. The old kits you could adjust it using an allen wrench in the vacuum opening.
3) The springs in the distributor may provide more advance than a stock engine needs. The springs can be swapped if this is a problem.
It takes some fine tuning to get base, vacuum advance and mechanical advance timing where it needs to be with this kit sometimes. You want timing set properly so you get decent performance and good MPGs but with no pinging.

I changed it to 10*, starts 10X better, and runs like a champ!

You're probably gong to have to set it at 5 degrees with a stock electronic ignition instead of the lean burn.
