The fuel enrichment is electric. As the engine runs, a small plunger like device warms up and pushes out. That then closes off the enrichment orifice shutting off the extra fuel needed for a cold engine.
As long as you hooked up the electric connector and everything is working properly, that shouldn't be an issue.
You may need to adjust your idle air mixture screw on the carb. Try setting it at 1 to 1 1/2 turns OUT from a lightly seated position. (turn the screw IN until it just stops, then back it OUT 1 full turn)
Pretty sure i know the answer to this already, but do you know what size jets are in the new carb VS. the old one? You may need to rejet the new carb.
