carb help

The points and rotor and cap was replaced a few months ago. I am going to convert to electronic soon, i am waiting for the ecu to come in the mail.
I just gave in and bought a reman carb, I don't have time to tinker with it. I bought new plugs also. I will put them in, in the morning. I know the rings are good the engine was rebuilt around a yr ago. I had my uncle mess with the adjustment screws because the carb was messing up and believe thats what fouled the plugs. The carb that is on it has to many vacuum ports and always had problems with it, I will put everything on in the morning and see what happens.
