Can’t figure out carburetor
10 BTDC and 4-5psi will start car, set from there. Belching smoke and fire is not good. confirm spark plug routing for an RB (CCW) 18436572. Popping carb sounds like firing order/plug wiring is wrong. 5/7 are next to each other, common to mix up.
See if boosters are dripping fuel at idle (fuel level too high or too much pressure), careful looking into carb during idle, use a mirror or video it with cell phone. check Edelbrock for a missing vacuum port plug on rear base, they come with it unscrewed rolling around the box sometimes.
