I'm just know thinking of starting to drive my II. I have the 302 with a Holley 600 vac sec carb with electric choke. My problem is when I cold start it, the butterfly closes properly but the idle doesn't kick-up like it should so I have to stay in it to keep the idle up. From what I have been able to find so far cold and operating properly the fast idle circuit should bump the rpms up into the 1500-2000 range until you blip the throttle after it's warm. The electric choke mechanism seams to work properly, butterfly closed when cold then opens fully when warmed up. So I'm guessin the fast idle is out of adjustment, since i have to pull the carb to get to the fast idle screw can anybody pass on any wisdom on the proper setting.
