After a thorough disassembly and cleaning, what can I expect from propane
use outside in 40ish temperatures?

Steve

I see propane boils at -44 deg. F. so temperature is not your problem.

There's more to the situation than the boiling point of propane.

It comes down to how many btu's/hr you need to get into the liquid
propane
in order to vaporize enough propane at reasonable tank pressure to
satisfy the appliance demand.

That's why when frost starts to form on an "in use" propane tank, the
heat transfer is "barely working" and the appliance is likely being
starved.
