Any number of things may be impacting your cold running problems. To start with you cannot adjust the carbs if you have ANY slop in the linkage. So that must be fixed before looking at other things as a possible problem area. New balls and sockets are available and are not expensive. The car can run perfectly with this original setup. Jim and I replaced the balls & sockets with aircraft cable ends that use roller bearings and there is zero play. It is not an easy conversion but worth doing at some point. Getting back to the cold running problem, I can always tell when my valves are out of adjustment by .001" or .002" because it will run rough when cold.

Yes timing is set at 3000 rpm. Don't pay any attention to what it is at idle. Also, once the slop is out of the carb linkage the carb linkages should be adjusted at full throttle not at full stop (idle). You don't drive a Benz at idle, right?
