I have a 1970 Spitfire MkIII, and with the recent colder weather, I have had some issues driving right after startup.
With the idle speed screw tightened enough for the car to hold an idle when it is started from cold, it idles at about 1700rpm once it has warmed up.
My understanding is that this may be due to a failure in the car's electric choke (it has a Weber carb), but I am not totally sure. How can I verify that this is the issue? Is there anything else that could cause this?
Thanks for your help.
