Thanks for that tip. I did try that and since the tank valve seems to have a leak thru, even when turned off, I think I still have pressure until I disconnect the tank coupling. Something I will deal with when I refill the next time.

Now, onto the LP gas fuel system.
From the quick research on Google, it seems the be made up with a converter, mixer and the carburetor.
If my problem is flooding, then where should I start? Hmmm!
I would assume the liquid fuel would be converted to gas through evaporation in the converter and that process would account for the frost I observed on that case, since the coolant temp wasn't yet high enough to assist in that process.
Not sure what the Mixer does??

As I search ebay, I see there are parts kits for the carboretor but nothing for the mixer or converter. I don't see any adjustments on either of the latter. The carburetor only has an Idle adjustment. Three is some kind of adjustment in the lower carburetor mount plate that looks like it not be "field serviceable" (seal wired).

I'm going to go back to google and search for other trouble shooting help.

Still hoping someone here will have some "Sage" advice?

Thanks
Steve
