Not the only one with the issue and here are a few things others have found.
Check the rod from the pedal passing thru the carpet and floor hole to make sure it is not binding or scraping the side of the hole thru the floor and that the accelerator pedal bottom end is not bent or the retaining pin is not out of the bracket on one side letting the pedal cock. Look at the pivot assy on the engine side down at the low part of the firewall. Make sure nothing is bent so one of the arms might be catching on the housing portion or that there is no dirt or caked on crud that might be binding.
Check the bracket on the firewall located roughly above the starter motor where the vertical rod from the accelerator pivot assy connects to the rod across the engine. The two sections are held together by rivets thru a rubber cushion. If the rubber has deteriorated or fallen out the top thin part of the bracket where the horizontal rod passes thru can twist or swing back toward the firewall. If it is moving the motion might be allowing some stress or a bind on the horizontal rod at the carb side.
Sometimes additional springs have been added because the original might be a bit weak. Too much tension can take a bit of pressure to overcome and then the linkage jerks as it overcomes the spring tension and breaks free.
