Did it run OK before the fuel pump died?
Can you choke it and get any different response from it?
Did you change anything other then the carb clean out and fuel pump rebuild?
A few things to check,
first, pull the fuel line at the carb, and put a hose on it down to a bucket. Crank it over and see how much fuel its pumping.
If its just a bit, your pump is bad or rebuilt wrong, if its a lot, go back into the carb and check for trash in the jet or a passage ways.
Set the dwell and timing, by ear, by light, or by vacuum. Get it close, where it sounds the best.
Check for fouled out spark plugs or crossed plug wires.
Even if a plug wire is on the right plug, it can still cross fire if the wire is questionable.
Check for vacuum leaks at the carb base since you had it off, and check all the lines going or coming from it.
Its unlikely anything major has gone wrong, cam wear will creep up on you and bent or bad push rods make noisy.
