AC Failure & Restoration questions

Hey, that sounds great. I think I remember it always taking less duster gas
than 134a but not sure about how the amount compares to R12.

The OP from the other forum says the charge by weight for R152A is 20~22 oz, based on molecular weight. Since it sucks to wade thru 40-ish posts to find relevant info, I packaged the OP's instructions into a single handy PDF file - see attached.

There may be another reason why I couldn't get that full 2nd can in.... In order to retain my AC & PS with the FFE crank trigger kit, Angry Stig came up with a brilliant solution using a backwards mounted spare FC Alt/WP/air pump drive pulley & some AL spacers. Since those pulleys are smaller in diameter than the stock AC drive pulley, I'm now under driving my AC a wee bit. So it is very possible that when I was charging the system at 2000~2500 RPMs per the instructions, maybe I should have been revving it higher to draw that last can in?
