OK. So I revised the vacuum connections and it made a huge difference. I plugged the port on the carb labeled "full manifold" and hooked the tranny directly to the intake for vacuum.
I did hear a knock so I am guessing that atthis point the timing is too far advanced and will be checking that tonoght and getting that corrected per you instructions above.

As far as the timing goes. The guy who I bought the truck from had the distributor advance line hooked to the intake manifold also. I now have it on the metreing block as you would suspect. Is this the reason I needed to advance the timing in order to get the truck to fire up with the new carb on it? Is is bad to have the distributor hooked to the intake? Does the port on the metering block draw enough vacuum immediatley to activate the distributor advance?
