I have a 2200. When I do a run up and check the ignition at 2000 rpm there
is no drop in rpm either left or right. Is this normal?

Bob,
Try it at a lower RPM, say 1600. You could expect only a slight drop (eg
<50RPM) which may not be perceptible at 2000.

Re the mag drop - Check your coil to flywheel gaps -
