Or so I thought....resealed the HSN assembly, this time very meticuously.

Surprize!!! Cool as a cucumber. As a matter of fact, about two full turns on the HSN cooler...something was leaking somewhere. 265 was as hot at it would get, that was with a nearly empty tank & a long romp through thick alfalfa after missing a turn.

Perhaps in the future I'll check what you guys with experience recommend first...live & learn.
