Okay, so what get's change in the R134a conversion apart from the fill
fitting and seals? What allows it to operate at higher pressures? Seals?

After sitting over-winter last year, mine was blowing lukecool. I put one
12oz can of 134a in with leak seal and oil included. It got the system
pretty darn chilly even at the front vents. I would estimate 50F on a 80F
day. I would have put more refrigerant in but I don't know what pressure to
fill it to or how to know when it's done with no sight glass to look for
bubbles in.

cheers,
