The mention of "high altitude" jets for the 182a is interesting,
but I wonder at differences of 182a and 182b.  Maybe the
burner box is different(?)

My '87 (of course) has the 182b.  It has run fine many times
camping (just last week, for example) up to 10,000+'.
In fact. it has run fine more than once up to ~13,000'
(Cinnamon Pass)  My pressure is 11.5" from the regulator.
Last week it ran for 7+ days, from 5,400' to 12,000'
to 5,500' to 10,000+', etc, etc, and back to Boulder.
We had Barbie ice cubes for our Margs at Lynx Pass.

It would be interesting to know the difference 'twixt
#24 and #22 orifices.

I have thought of Paul's situation where the bench-testing
fridge worked fine until he added the vent cover.  The only
idea that comes to mind is the angle of the vent.  When
installed, the vent is vertical.  If I take my fridge out
the flex tubes "flex" and I'm sure the angle would not
be vertical, so if I put the vent cover on then, it would
not be exactly the same as when installed.  Maybe this
could account for the difference in performance(?)
I can't think of any other reason for the vent cover to
be a problem when bench testing.
