This is a vacuum diagram for the Weber carb or basically what I have except I do not have the CTO valve and EGR valve. If you remove those lines from the diagram that is exactly how I had mine setup. Right now I just disconnected the Dist line and capped it. I'm a bit confused about putting a Tee and check valve in the line?
I think there is a spring unhooked inside the Dist. because after timing and reattaching the vac line to the Dist you can watch the vac advance seemingly all the way advanced. HEI is scheduled to arrive today. If I get all the instructions read and I can borrow my neighbors heated garage I might have it in this weekend. Check compression, Balancer alignment and timing chain slack. But that's a long list because I have to replace a hydraulic line on my plow today and a few more chores.
