If you do note the oil level in the onboard tank is low (tank must be completely full) purge it by hooking up your water flush attachment, starting the engine (neutral and level) with top cowling off, loosening the oil reservoir top and allowing it to fill to overflow (have plenty of rags). Re-install the screw on reservoir top with the engine still running and only at the point where the tank is overflowing. Hand tighten only until the screw top is just snug. Do not overtighten. Youll strip the threads or crack the tank if you overtighten.Thats how I fixed my problem. No problems since.
