Don't see where you set the choke yet.. so I'll give some highlights to get her goin'..

first thing in the morning, with the air cleaner off!

open (keep open) the throttle about 1/2 way, with the fasteners for the choke spring housing loose, turn the choke housing so that the choke plate (butterfly) opens and closes. With the plate just barely closed, there should be lines under a pointer at the top, after the plate closes, go one extra line. (turning the cap in that direction is called "richer", turning the cap so the butterfly opens is called "leaner")

Tighten the choke housing and behind the housing is a cam, make sure the cam has the fast idle screw hovering above the top step.
Release the throttle from the halfway position and double check the fast idle screw is now on the top step of the choke cam.

If all looks well, (pump the throttle 2 or 3 times and start the motor without depressing the gas pedal. After startup, if the idle is to high or to low, you can change that on the idle adjustment screw behind the choke housing. If it puts out black exhaust, you'll need to lean the choke out by turning in the opposite direction that you did to close the plate.. Or if it starts and dies quickly, it may need a richer choke so you'll turn it in the same direction that you first did to add another line at the top.

After a moment or two, you should be able to "blip" the throttle and it should come off the peak of high idle, but still be on the high idle cam.. The engine should be turning maybe 8 to 1000 rpm and should be fast enough so that it won't die when dropped into drive.

Once the engine is mostly up to full temp, the choke should already be wide open and you'll be on the regular idle screw...

There's the quick and dirty FoMoCo choke adjustment... been doing it this way for decades and it should work for you. Keep us updated as we'll be waiting for news!
