Injector Bleeder Valve

Hi Friends,
I am having a small brain "fart" with regard to my injector/fuel bleeder valve. Our engine is the Universal M25XP. I am referring to the knurled knob on the starboard side that bleeds the injector lines of air. My question is: Which way is closed/off? Should I turn the knob all the way in or all the way out for normal operation. It seems to run fine either way. Nonetheless, what is the correct way to position the bleed knob?
Thank you all for your prompt response.
Cheers,

I believe the manual says - closed.  Some folks run it 1/4 turn from fully closed to provide for some return to the tank before the injectors.

Hi Les,
Thanks for the reply. So is that screwing the knob clockwise, all the way down? Or vice versa?
Thanks again

Righty-tighty (i.e., clockwise) to close.
With the engine off but the electicity (i.e., key) for the engine on, you should hear the fuel pump clicking quickly with the valve open as it pumps fuel back to the tank, and as you close the valve the pump should start slowing down.
