Holley Idle Sticking

[kj1963falcon]

I am having problems with my throttle sticking and it has me stumped.

Last weekend I installed a new throttle cable and mounting bracket from Lokar and with the truck off everything moves smoothly and works great. The problem is when I fire the truck up the throttle sticks even once it is fully warmed up. Even if I work the linkage by hand I can feel some resistance, but as soon as I turn the truck off everything moves nicely.

Does anyone have any ideas

Try some WD40?

How old is this carburetor?

I did try some wd40 and I also sprayed some carb cleaner around and in the carb to try and fix any sticking but it didn't seem to help.

I don't know much about carbs but i kind of feels like the choke is stuck on, which is providing drag on the throttle linkage?

The carb is a Holley 4118 with an electric choke. I have no idea how old the carb is, it was on the truck when I got it.

Check your plugs to see if you are running rich. You may need to adjust your choke and/or idle mixture.
