Kelly, pull your head out. It is not that complex. Under that plastic cover
with the 3 screws, is a flat wound spring with a square bend on the end. It
meshes with a piece of linkage connected to the choke plate internally in
the carb. That is why you could not detect any linkage. When the engine is
completely cold, loosen those three screws, (no need to remove them
completely), and rotate the plastic cover until you see the choke plate
move towards the closed position. If it opens, you are turning it the wrong
way. Turn towards the closed position until it just touches closed, then
tighten the screws. It is not a complicated adjustment. You can easily do
it. Your engine will thank you.

Kelly,
Should you be at the International Convention in Indiana next month, I can
grab a old carb and explain all the pats and how it works.
I was fortunate to have been playing with this style carbs from 1960 .

I'll do this tonight!
thanks again all. I won't be at the convention, some year I hope to make it.
I've been so happy with my GMC, I'm a year+ in and can't help but smile when I drive it, and it is the best party bus you could want at one of our festivals
I'll report back tonight what I find

Kelly, look for signs of black smoke out the exhaust after the engine is at
operating temperature. And, the choke plate should be vertical. If black
smoke is what you see, make a very slight adjustment to the open direction,
and try again.
Good job by the way.

It seemed like dark smoke, so I opened it up, the choke was still slightly closed. I rotated to open it started it again.
now white smoke. I can't remember if it smoked like this before. Course there's probably extra gas/etc in there. I should take it for a drive (unfortunately getting in/out of the driveway is the worst part of any trip...)
White smoke is OK? Water?

Noise is from the fuse box, I shook it and it stopped. But yeah, I should get that. The plunger to tell me the door is open/closed is broken so it randomly shows open. I should just remove the relay. Is it on the top of the fuse box or was I just lucky?
James Hupy wrote on Thu, 17 August 2017 19:25The door buzzer can be defeated by pulling the ignition key out a little
bit. It is part of a necessary relay, but there is a replacement relay that
does not have the buzzer. Call Jim K. He will stock it.

found them online for 35 cents each.
I ordered 10.
I put the original back in, no leaks that I can see/smell. Fingers crossed

Kelly, 'twas all done in fun. I figured if you bought a GMC MOTORHOME, you
certainly must (like me and many others here) have a twisted sense of
humor. I meant you no disrespect, that was just a gentle prod meant to
encourage you to action. Now you know, through firsthand experience, that
setting the automatic choke is a fairly straightforward process. You can do
it. I have confidence in you.
Welcome to the wild, wacky, world of gmc's.

No offense taken at all! And since I was able to do that I went ahead and changed the carb filter.
Today I'm changing a steering wheel and cleaning the fridge burner.
