Did the first extended drive today on my stock '41 V8 coupe. Throttle response is awful. Got home and fully analyzed it. It's all mechanical. When I operate the gas pedal, the throttle rod connector fitting pulls all the way open before operating the throttle lever on the carb. Either the spring is weak on the connector or the shaft takes more effort to rotate than it should. Once the throttle lever on the carb starts operating, the accelerator pump linkage starts torquing itself up unnaturally taking all the slack out of the linkage and moves about an eight of an inch before the pump actually moves and gives a squirt.

It drives just like you'd expect with those observations: press the accelerator a little bit and nothing happens while the spring on the accelerator rod connector to carb opens, a little bit more and the throttle plate starts to operate and the car moves slowly, a little bit more and suddenly you get the pump squirt and the car take off like you stabbed the accelerator.

Just rebuilt the carb with a kit so I've done the best job I can do without sending it out to a Holley 94 expert for a professional rebuild.

What should I focus on:
1. accelerator connector fitting to the carb
2. carb throttle shaft
3. accelerator pump linkage.

This car is going to get hot rodded a bit so I don't see myself spending money on a Holley 94 I don't intend to keep. Just trying to get it running correctly in a stock configuration without spending a lot of money before making modifications.

Intentions are either a single single new super 97 or a 97 dual carb setup.
