It sounds like it is running too rich. Check to make sure the choke is adjusted and not sticking shut.
Block the choke open and see if the vehicle runs better. If it does, that is where the problem is coming from. If that doesn't solve the problem, it could have to do with a bad float in the carb, a bad needle valve, or the air fuel mixture may need adjusted.
