Loud crack from accelerator pedal.. no power, kicks back in?

As the title says, my 1985 C10 has a problem where the pedal will make a loud click, (i can physically feel it) the acceleration stops, and then suddenly kicks back on. What could this be?? I think it may be a linkage issue, but I'm not 100% sure.

The throttle cable or linkage is binding. Rusty cable? Throttle plates in the carb could also be an issue.

Think you diagnosed it. Just gotta find exactly what is bound up

Decided to come along and update this since I have found the issue.

The secondaries had been over-torqued and was binding on the carburetor.

Check your secondaries by physically pushing down on them and making sure they move and rebound without sloppyness but also not getting stuck.

For me, the carburetor's left butterfly on the secondaries would stick on it's peak close.

I managed to fix it by finding out it was so stuck that the plate had warped in the position, mind you I never had touched the butterfly up to that point other than during my rebuild of the carb in February.

Godspeed to anyone that sees this!
