Hi David,
It does sound like it's running lean on the high end. The solution is

enough load to slow 'er down. At full throttle is sounds like pro
So instead of giving it away I rebuilt the carb and half dozen other fixes this
winter.
Runs and idles great, but at full throttle she bogs down continues to run, but
sounds rougher.When out gear it goes right to full throttle.
Perhaps overpropped?
