Getting enough vacuum to add 4 degrees timing tells you that the idle screw is adjusted up too much. Carb is idling on the power circuit. Idles rich.

You nailed it right here! Since it has idled more than anything with the screws adjusted out too far it basically flooded itself constantly. I made sure the timing was at 8 degrees again. Pulled all the plugs, cleaned the carbon or gas off of them and stuck them right back in. Hooked up my vacuum gauge set the mixture screws correctly. Rehooked the vacuum advance, now I can't tell how far advance it goes. It runs smooth. I took it for a ride and was able to spin it to 3500 rpm without any hesitation whatsoever! This truck hauls some ass now! Thank you!!
