Idle acting crazy

I will check & see if it is dripping fuel at all tonight. I know I smell fuel all the time. I am running a stock fuel pump, I do not know what psi it puts out. Would flooding the carb cause the idle to drop like that to where the car almost seems like it is going to stall but then recover just from putting it in neutral? I have never messed with the float level. I guess I need to do some research, is it hard to adjust? Thanks for the advice.
