I checked the throttle cable and I can see it is not wrapped.
All the linkage seems fine, and I have the idle screws all the way out. I am even running an extra spring on the throttle bar to ensure that I get full return. Nothing seems to be binding. I am running an old original distributor with the injection point set removed, and the vacum advance disabled. Am I wasting time chasing throttle cable functions or is it just the stinking distributor? |

When you say that the throttle is sticking, do you mean that the idle RPM is too high, or that the throttle pedal doesn't come all the way back up?
If the former, check for vacuum leaks. If the latter, try to isolate the problem. Disconnect the throttle cable from the throttle body. Does it still stick? Disconnect it from the pedal. Does it stick? Check just the throttle body. Does it close all the way? Isolate the problem. When you have it down to one or two systems, you can check them in detail. Note that the bores in the throttle body where the valve pivots ride can and do wear. That sometimes gives you a sticking throttle. Heavy springs will tend to exacerbate the wear. --DD |

QUOTE(Dave_Darling @ Nov 16 2013, 07:59 PM)  When you say that the throttle is sticking, do you mean that the idle RPM is too high, or that the throttle pedal doesn't come all the way back up? It starts out with a decent idle but when I blip the throttle it seams to stay up. When I drive down the road, by the time I get to my turn around, its up about 3000 rpm. If the former, check for vacuum leaks. No Vacuum If the latter, try to isolate the problem. Disconnect the throttle cable from the throttle body. Does it still stick? Disconnect it from the pedal.

New Carbs, should not be any wear. --DD |
