high Idle 318

Dakota R Keck said

The fast idle cam is staying where it idles high i have to adjust it to where it isn’t idleing super high. If not adjusted it idles high and diesels. Once adjusted it runs great i was more or less trying to figure out the culprit, i daily this thing and this is my only issue and i dont want her laying down on me.

Assuming the fast idle cam can fall down by gravity as it should when the choke is fully open then the idle speed is controlled by the other screw that stops on the large fat screw on the carb.


Some photos of your carb would be really helpful both left and right sides


shot in the dark... the distributor advance is pulling in too soon and speeding the engine up.
