Looking Good...
I don't think you need that resistor.....check the instruction or visit their web site.
The idle vacuum has to come up. Are your windshield wipers connected...? any chance of a small leak in that system??? The only time my vaccum gets that low 6 ......is if I floor the gas in 3rd or 4th gear.
Steady vacuum reading is encouraging...... whatever is leaking must be very small and easily overcomed by the higher rpm.
You are going to have to get very close to the intake manifold, carb base, wiper output pipe, dizzy vacuum advance......check the PCV system as well........ may be stuck open...... take it apart and clean it in carb solution......
Cheers
