On my old VRO I would mix oil with gas until I saw the oil level in the oil tank drop and I knew the VRO was working.<br />On a Ficht equipped motor that test won't work because oil/gas mix would go into the cylinders via the injectors and bypass the lower end of the motor. <br />Am I correct that you can not operate a ficht motor on an oil mix? The oil needs to spray directly into the crank case via the oil pump.
