Raise engine IDLE speed 200 rpm.
That should solve the problem.

Also advance timing or at least check timing at idle speed.

Original factory specs (OF ANY ENGINE MADE AT ANY TIME BY ANY MFG'ER) usualy indicate a rather slow idle speed than what is practicle for REAL WORLD operation.

Raise idle speed to at least 500 rpm. ESPECIALY if it has AC.
