Are you familiar with the tuning procedures? Can we assume that
the ignition system is in good tune and timed properly? Is the carb
throttle plate stop, idle bypass screw, and idle mixture screw set up
properly?

If so, it's probably carb icing as already pointed out. Just below the
base of the carb, is it frosty? One easy way to verify that icing is
causing the problem is to idle it in your driveway with it acting up.
Direct a heat gun (or hair dryer) into the air intake and see if it
goes away. Then you'll know where to direct your efforts.
