I am having trouble with the throttle linkage on my 1957 wagon with 312 and Carter four barrel. It doesn't want to return to the idle stop. Somebody has added an additional spring going forward which solves the idle problem but due to the increased pressure it causes the override portion of the linkage to operate which reduces the linkage travel. It overrode this feature with a bolt and nut but it doesn't fix the underlying problem. Also with the additional spring the pressure to operate the gas peddle is higher than necessary. I've attempted to follow the shop manual procedures for adjusting peddle height etc. but the problem with not returning to idle still exists.

I'm stumped at this point.

Thanks
