That's a lot of info right there. Thanks. I will have to look at the carb itself to see how the slots are. I know when at idle I am getting no vac at the distributor. But I will double and triple check that with a guage. My van originally came with the lean burn box of crap that only controlled the timing and not the carb. I should have kept it but I have a habit of throwing stuff out that I don't use after a bit. I'll check it with a guage today and get back to ya.
