It does have a vacuum actuated pull off that opens the choke butterfly a tiny bit, which is not adjustable. I guess I could try tweaking the rods for the choke butterfly.
That's it. Some sort of mechanical rod or notched plate determines the amount of position difference from non-running to running.
You say its great when warmed up - so thats why I'm focused on the choke during cold running.
although I bet AJ will say something is not correct if the throttle mix screws are having no effect once warmed up.
If you can turn them in until they just close and still no effect - I too going to say that something is not quite right.
