not saying that is your issue, its a good idea to check all the things mentioned above, but if there is no binding in the cable or pedal bushing issues, it could just be the resistance of the secondaries youre feeling.

thx...just started after the recent rebuild so you may be right

The lockout is on the passenger's side and is not difficult to disable. The secondary throttle blade lockout, AND the secondary flapper lockouts on the earlier carbs are removed or disabled as standard procedure whenever we work on a quadrajetjet.

If it's the original cable, it would be worth removing and inspecting the movement of the cable within the sheathing to verify that's not the cause.

I replaced with a Lokar cut to fit cable which is very nice.

thx, another item on my list to check :-)

replaced the cable, i think around $25 and smooth as butter. install took maybe 15 min
amazing difference in the enjoyment of driving the car

thx

It should be the carb since the problem popped up after the "repair". Been reading the replies. I don`t think the accel pump or pump rod binding has been mentioned. Rod could be installed incorrectly.

Check carb gasket interference also.
