I am working on a 1930 model A street rod with a 350 engine and a Holley 4 barrel carb with mechanical secondarys. I have installed a spoon type gas pedal. There are 3 holes on the lever that moves the cable and I have the cable in the top hole. I have played around with it, and when the gas pedal in fully depressed, the throttle plates inside the carb are only 3/4 of the way opened. I can not seem to adjust it so the throttle plates will open completely. Any suggestions on how I can do this? Thanks

check the plate linkage, if everything is in order, then just try to find a way to shorten the throttle cable or make some kind of bracket that will allow it to pull further and is maxed out when the pedal is maxed out that way you have complete control/extension of the throttle from the pedal.. hopefully this helps.
If all obstacles are clear, then you need a longer throw on the pedal and/or shorter on the carb linkage.
Stop built into the gas peddle
Yes, I can manually open the throttle plates all the way buy pulling the cable back and additional 3/4 inch. It appears after closer examination that there is a stop built into the gas peddle which limits the travel. I might be able to grind this off to allow the cable to come back enough to open the throttle plates completely.
