Question: Fast Idle Stuck On

[Jack64]

Thanks to LLC5 got engine timed and off we went to a Corvette show Sunday. We received rave reviews.

On the way home, the fast Idle Stuck On.

1) Checked fast Idle screw. It is tight- has not moved
2) Cam and linkage free-working unimpeded
3) Choke loosened. When rotated, it does NOT move the butterfly. It is free wheeling.
4) Butterfly is easily moved by linkage

A) How does the choke attach to the lever that itself is attached to the linkage that operates the butterfly?
B) Could this be the reason for the fast Idle being on?

Pics of choke and lever attached.

Many thanks.

Just realized the loop on the choke bi metal spring must accept the armature. Will adjust and advise if Idle corrected

Yes, the loop goes over the protruding linkage arm. There must also be power and ground to the coil with the engine running for the coil to open the choke butterfly and drop the fast idle linkage.

Thanks again, LLC5
I positioned the armature in the loop of the metal spring, and voila!
Idle down to normal (900 rpm)

Excellent, good work.
