Re: Delay in throttle response when giving it more gas
There is no inline valve that switches back and forth between venturi suction and ported manifold vacuum. It's all modulated within the carburetor. Max of about 4" of vacuum at the distributor.
I would investigate the accelerator pump like Lanny mentioned above in post #3. It is a rubber cup piston (not a diaphragm).
Also there are two holes in the throttle lever for the accelerator pump link to attach too. The outer hole will give you a quicker, and longer pump stroke. Also make sure the accel pump rod moves down even with the slightest throttle movement. Might be some slop that delays the squirt. Or internal carb issues with it. I've done hundreds of these carbs, and it's amazing how many things are assembled incorrectly. A difficult carb to get correct.
