That's exactly what I was referring to. The car is miserable to drive if there is too much throttle pressure. Sometimes, there is a problem with the throttle sticking just off idle (about 12-1500 rpm) This is very annoying, also. A stiffer return spring IS NOT the solution. Instead, fix the reason for the throttle sticking. I've found it usually happens only when the engine is hot. The only way I've found to fix it is to disassemble the center carb base and provide a minimum of .003" clearance between the brass shaft and the cast iron base. This is true whether the bas has had bushings installed or not. Evidently, as heat increases, the clearance decreases and causes sticking.
If anyone else has ideas on this issue, please chime in.
