Your symptoms would usually point me to points being too tight, but since you have electronic ignition that gets a pass. So next that points me to a carb issue or possibly the governor. Next check the fuel flow to make sure it's not starving for gas at higher rpms. I also keep a spare coil around to rule that out with an easy swap. I have saved myself a lot of time chasing other things with a simple coil swap. That way no adjustments get out of wack and it is clean and easy way to check connections as well.
