My '78 305 & 350 had a Holley 600cfm with the choke mechanism removed and a
aluminium street scoop. In cold damp weather, it would idle / drive rough
if driven straight away for upto 20 minutes or so. Letting it idle for 3/4
minutes then stopping it for a  minute always made it run sweet. I always
attributed this to carb icing but never actually knew if this for sure.
