car running very funny

Ok so this is the second time I have posted this and I have found out a number of things that arent wrong with my car, but lets start with what it's doing. Every morning I go out and start my car, and it takes sometimes a few seconds of the starter turning before it turns over the engine . When I drive it runs very rich and smells of gas at every stop. It also idles very low and stalls on occasion. I've noticed that it only stalls when my foot is off the gas, Whether I am driving or at a stop. I know it isnt the dizzy or timing or fly/clutch. Only thing I can think of is that I put a 190 lph holley fuel pump in it and the only other performance parts I have are fly/clutch and exhaust. I was thinking maybe the fuel pump is either installed incorrectly or pumping more gas than the car can burn and flooding the engine. Please help I'm about to take a bat to it
