Hot Start Issue Choke stuck?

There is an opening on the bottom of air cleaner snorkel, a flexible metal hose connects to a shield on exhuast manifold.
On damp days below 65 degrees the carburetor will form ice inside,cutting off fuel.
I witnessed this on my power wagon,it would start fine,start to warm up, then out of the blue it would stall.
Wait 10 minutes and it would be fine.

The morning i caught on,i had hood open and could see base of carb frosting up on the outside.
Added the missing parts and to this day,still starts and warms up without issue. 17 years later.
