i have a 68 mustang that in the morning when i start it up, it idle's real high i have to press on the gas to bring it down to normal idle, its got a edelbrock 1406 carb on it when it's warmed up its fine any help as to what it could be or what i could check.

 

it's the choke setting.

check on page 15Figure 11. open (loosen) the fast idle screw by one turn and see how that works for you
