Another Edelbrock issue

[6768chevylover]

I've been reading post about edelbrock 600 carbs.. Of course I have a 1406 carb with the electric choke and my issues are similar to the ones I read with the high idle in the cold but no one seems to have the high idle even when they come to a stop when the truck is warmed up. I'm always bumping the throttle to bring it down and sometimes that doesn't work. When I do bump it I always smell gas. I've also noticed that sometimes when I need to get going when I'm driving, I feel hesitation and then it just opens up. Its an older carb and my first time owning an edelbrock. I usually have holley carbs. Any thing I should be looking for?
