You may also try adding an extra spring (or rubber-band or miniture bungi cord to help the return spring). It may make the peddle a little heavier but depending on the spring/rubber you pick and how you rig it - it can work very effectively. My 80 camaro had a similar thing - and it was just that the return spring was old and tierd. A helper-spring fixed it just fine (it was about 1/4" x 5" and over-stretched to the hook-on-points). I rigged it from the throttle-hook-up to a bracket on the valve-cover. On my Harley I use a bungi to help the tierd break-peddle return-spring (similar situation
- though not as safety critical). Elliott
