The divorced choke should lift the fast idle cam to the highest position and tightly close the choke flap when you move the throttle once on a cold start. At the same time the accl pump will put a shot of fuel into the intake.

If the choke flap isn't going completely closed the link is too long or the choke coil isn't working correctly. Could also be a linkage issue with the carb but the first statement assumes the carb is correctly assembled.......Cliff
