Good morning folks.
Me and my big mouth. Many people know I upgraded the AC in my 911 long ago and I know a little about automotive AC systems. Anytime someone asks for my help I tell them I only do R-12 systems and I didn't want to contaminate my equipment with 134a. That gets rid of them. Except a friend in the Porsche club has a old air cooled 911 that has never been converted to 134a. He is coming over tonight so I can help him with a little AC work. I guess that is what friends are for.
