Re: Carter WGD Fast Idle Question

The green bit is supposed to have a tab that touches the bottom of the purple bit as the choke rotates closed. This holds it and the blue bit lower than they would normally be. When the blue bit is held low, it pushes down through that bent rod onto the throttle arm.

The orange doodle is only for unloading and is not directly germane to this discussion.

The usual problem with these carbs is that if someone takes their hand and forces the throttle back to slow idle while it is still on fast idle it will go: either the bent rod or the little tab on the green thing that touches the purple thing will bend out of position and voila, no more fast idle.
