440 engine,, EB carb... Car goes 35 mph at idle,, I did everything I know to do to slow it down... Even tighten return springs,, And it's not the throttle cable set back too far,, I can pull the throttle back by hand and it will go to 750 rpm...Not the choke,, not the idle screw, not the choke,, not the cold idle cam,,, but when I shove the accelerator down, same problem,, And it seems as if the 4 barrel never kicks in.. A friend of mine has a 65 chevy, 350,,, has the same problem.. any ideas? Thanks...
