Mike without seeing your VOM it's hard to know,but I think you're on the right track. Try putting the clamp over the plug wire and see what you get. If the reading seems extremely high divide the reading by four(some ignition systems fire on every stroke,not just the power stroke).You can tell by the sound if you are within range(bike won't stay running much below 750rpm and redline is around 6500 rpm).
Adjusting idle is fairly simple,just locate the throttle cable connection at the carb and look for a screw on a linkage that moves as you twist the throttle. The point of the screw rests against a stop on the linkage when the throttle is at rest. Adjust the screw in(moving the plate away from the stop) to speed up the idle.Move the screw out to slow down the idle. Just remember the starting point and make small adjustments. It's best to have the scooter warmed up to operating temps before adjusting.
If I've missed something in the process others will be along to square you up!
