When I used a choke I remember just waiting until a cold morning then loosen the three screws and turn the housing until the choke is almost closed then tighten the screws. Give a couple pumps of the throttle peddle and fire it up, it should stay running on it's own. If not, adjust the fast idle cam a little. Drive it around until the temp gauge is moving up to it's normal position, blip the throttle and it should settle down to the regular idle speed. Pull over and see if the choke is fully open. Never paid any attention to marks. -BA
