Carburetor choice

I don’t use initial timing. My distributor was built by a guy and it don’t have vacuum . I run between 34-36 total
Sir, everyone uses initial timing. The initial timing is where the distributor is set when the engine fires and at very low RPM. After a certain RPM, centrifugal force moves on the springs and the counterweights inside the distributor to produce additional timing. You don't have a vacuum advance, so that will not play a part in your timing. The initial timing plus the various timing increases due to centrifugal force will equal the total timing you mentioned of 34-36. There is a lot of performance tuning available through the distributor, so that is another avenue for you to optimize your vehicle.
