Re: Gas Pedal Sticking....
Dan, thats a tough one to diagnose without seeing. I'd take the spring off and manually move it through its range of motion at the carb, check for any tightness or binding, then if you find nothing put the spring on and do it again. You may need the wife to push on the gas pedal as you watch things move, you just need to eyeball everything as it works.
I've seen the spring drag on the linkage of the carb at full throttle if its mounted too low at the stationary end (oposite of the linkage), that might do it, but you can bet it's somehow connected to the new carb unless the linkage at the firewall got bent during the engine swap.
You don't need crazy spring pressure, but it should be decent but not too heavy at the pedal for comfort, and a double spring for safety.
