i need help on where to start! (carb setup)

Set the throttle blades to expose about .025 of the transfer slots when you look at them with carb upside down, then screw in all 4 idle mix screws till they bottom out and then unscrew them all out 3/4 turn each...then disconnect the vac adv if u use one at all.and plug the vac line at the carb.... then roll the motor over with a breaker bar with the key on and have a friend with dialback timing light set to 20 degrees watch for the flash as the balancer lines up with zero mark. Do that and adjust the distributor till you get the 20* initial. Snug the disttibutor down some and then start it up and see what u get..
