Hi guys. My s2 still wouldn't start due to fuelling issues. Had to hold metering flap down to get it going.

Then I crimped the hose from the oil separator to metering unit while my mate cranked it over and it fired up first time.

So I blocked this off and now vent to atmosphere through a mini k&n filter.

Does this mean I have basically overcome an air leak engine side so now the flap has enough vacuum to pull down and send fuel through???

Starts first time now and runs sweet!!!!
