here is something i want to add.... my truck runs great.... i have the hai diaphram, thermo valve, and mc valve plugged off @ the carb... my timing is set to 0* and idle speed is set to around 800 rpm... recent plugs, wires, rotor, cap
lb, im still ver ywith the idea your vacuum stuff is wrong or off.... the distributor timing can effect the vacuum as well..... the distributor being off can effect everything you are experiencing.....
