It's quite possible the choke was not fully open only 7 minutes after a cold start. I'd want to drive it at least 15 minutes before a smog test, and 20 would be better.

I started working at a Chrysler/Dodge dealership in 1975 and my new 79 PU had one of these carbs and I kept the truck for 14 years .

EDIT: Just had a thought ; Have you had the RV long enough to know if the engine is using any oil ? More than a quart in 2,000 miles ?
Engine oil going through the combustion chamber , either from rings or valve seals shows up as high emissions at a tail pipe analyzer.
Have you changed spark plugs ?

Hereís a pic Iíll post another later. I had a hard time removing that black thing itís attached to some hose I always scared to mess with.

The black thing is the air cleaner. It probably has a big hose you can see and a smaller one underneath. It's really not that scary (smile). The plate you see that keeps you from seeing the venturis beneath it (the "barrels") is the choke.

Was that pic taken with the engine warmed up, or cold? If warmed up, it's a picture of the problem because the choke is closed. If cold, it's normal.

You can run the engine with the air cleaner cover off. Warm it up and see if the choke plate opens. You might have to tap the throttle to get it to open as the engine warms, depending on how it's designed. I've long since lost track of which need you to do that and which just open by themselves.

It should be *vertical* when the engine is fully warmed up.

The choke plate should be vertical, as depicted in post #11, with the engine fully warmed up.
