Hi Mike,
One of the list mechanics wrote this up last year and I thought he was
dreaming or on wacky weed. However since cleaning the evaporator and
condenser and switching to r134a my numbers are right on with his and my 86
westy runs right down there with the best of them. I am a believer. I will
include his note from last year and since Michael Modl is a great guy I
don't think he will mind.

Hi John, it should be cooling between 40 to 48 degrees, depending how hot it
is. Your tech should be seeing a pressure on the high side of about 150 to
275 lbs, and on the low side about 25 to 40 lbs. If the pressures are even,
then you need an expansion valve, 4 hrs labor plus parts. If the pressures
are good, then with a small pin light check what color the freeon is inside
the sight glass of the reciever drier. If it's rusty brown color, than you
need reciever drier. If you are going to replace the drier, than this would
be the time to convert to R134. It will be cheaper to convert than stick
with
R12. Let us know what happens.
