I run mine, on synthetic two stroke oil, with the pump giving a drop every 2 or 3 second, plus I ad 1 % in the petrol.
The pump setting is next to nothing, start with high setting and work you way down.
Oil consumption should be 1000-1200 mpg.
The wells in your crankcase should be filled, it dips the big ends in this oil every stroke.
The problem with the oilpump, as I see it, is that it was built for SAE 50 oil, and is having problems handling thin oil, so go and find you a good, thick, modern two stroke oil, I use Agip Speed, do not use outboard oil.
Pumping 3-4 ccm oil through the oil lines would be a good idea, thus making shure the oil lines and the wells are filled
