Larry, Larry, oh dear Larry!! After all that time and trouble you still won't be able to sleep, knowing that time-bomb evaporator is STILL in there!! You were SOOOOOO close! Kinda like getting the prom queen's drawers to her knees and still going home blue !!! Just kidd'in of course, but as I recall you said you added some R-12 at the beginning. Do you know why you had to add some?
