Either the choke is sticking closed or just needs adjusting. That is the most obvious thing to check.

Simply lower your fast idle speed by backing off your fast idle speed screw. The '81 is an ECM-controlled carb, but the ECM does not control idle speeds. Set the cold rpm where you want it using the adjustment screw.

What do you consider "very high"? When the choke is closed on a cold start it is normal for the idle speed to be higher.

That is not the original carb for an '81.
Can you post the numbers on the side of it?

Does the wire with the blue plastic have 12 volts when key is in run position
Czy przewód z niebieskiego plastiku ma 12 V, gdy klucz jest w pozycji biegu
adjust RPM with screw in second picture to about 1,800 RPM
