I would take off the top of the air cleaner and inspect the choke plate. If
it is straight up and down and the engine is warmed up, that rules out a
stuck choke. Try to move it with light, one finger, pressure. If it moves
easily, that is not your problem either. Move the throttle by pressing the
accelerator and look for fuel sprayed into the primaries. If you see fuel
sprayed, it is PROBABLY NOT your carb. Look at the ignition. New modules
have been known to be bad right out of the box. Another frequently found
ignition problem is the connector that feeds the distributor. The coil
wires can be pushed back inside the cap and even if the plastic connector
is completely snapped into position, the metal to metal contact is faulty.
Take the coil cover off and look. It has educated me more than once.
