So I've had to blow the dust out of my head that covers carb and ignition tuning. My 85 350/465 blazer with a CCC dist and non computer controlled Q-jet (vintage/model unknown) needs to have some adjustments. I have a few questions. Pretty sure that the vacuum advance should not be connected to manifold vacuum, or should it? It seems to be working correctly if it should be connected manifold vacuum. BTW, the Dist had been jumpered to run like a normal HEI. Also, I'm 100% sure that I have a mismatched balancer/timing pointer tab. It appears I have small 6-6 3/4 inch balancer and a big 7-8 inch timing pointer tab. Any Ideas on how to make what I have work, or just go buy the right balancer? Any tips on I.D'ing Q-jets? Would love to rebuild this one and looks like it's a manual choke (blocked open), so I'd love to add an electric choke or just add a choke cable.
