"Eddie" AFB carb issues..

Hey guys,
Sorry for the delay, it's been snowing non-stop, and had to dig the car out. Literally a foot on the hood.
So after finally getting the hood open, I pulled the top of the carb off. Had plenty of fuel in the bowls. surprised me actually. dug around some more, and realized that the damn accel. pump gasket/plunger had come disconnected from the shaft! I was pissed. its a brand new Edelbrock 1470, DONT buy this thing. the four tabs holding the gasket in place are insufficient. my gasket loosened up a little slipped right off during acceleration.

Sidenote: I was at work during my original post, and forgot to mention that I have no choke in place. in fact, the ports to the choke are open, as I haven't bought an electric choke yet.

Anyway, new accel. pump, and gas is squirting properly now. thing is, is doesn't want to run right. or is still harder than hell to start rather. It tries to start now, but never really get going. after a few cranks, it will "pop" and puff white smoke indicating that its still running lean ( to my knowledge.) I haven't tried starter fluid, but with fresh gas, it shouldn't be starved. With the Accel. pump now fixed, is this poor starting issue just a factor of the ice cold weather and no choke now? Thank you.
