stalling with AC on, coming off of idle

OSAC has been disabled since I got her running a year ago. Dan’s posts on the slant six forum really helped for that.

All vacuum hoses were new a year ago. The only fouled piece was the plug on the charcoal canister which I replaced with a new plug.

AC was at 350psi high and 35 low. My notes from last year say that I couldn’t get it up past 160psi no matter how many cans I charged it with. That particular issue seems to have resolved itself. Today a pulled the high side down to 225 psi (it’s over 100’F here) and 30 psi low.

It still stalls with the AC on.

I’ll check the timing and air mixture next. Maybe pulls the plugs and do a visual check on them. Now that I think of it, every so often it sounds like it skips a cycle like a misfire.
