What could cause a knocking under load other than the engine. IS 2 STROKE . SOUND SEEMS TO BE IN UPPER PART.

Bad rod bearing.-----Loose piston.-----Or broken gears.-----Drain the gear oil for a look see.

Thanks for the help. Your reference to broken gears and draining gear oil is about the foot , correct ?

Loose steering link arm.
Loose beer can in splash well.

Pull one plug wire at a time and see if sound changes.
