Ian,

the OMP varies the amount of oil going into = the valve.=20

 

I have determined that = it just=20 with RPM, and the throttle lever connection cuts the flow way back at=20 idle,  but at not much above idle the flow valve is full=20 open.

 

The valve is actually

a=20 mini intake manifold in parallel to the main intake manifold. When the =

rotor sucks the mixture in through the = manifold, some=20 of it is going through

the little vacuum hose and the little hole = in the=20 rotor housing picking up

what oil the OMP got into the valve. This = oil is=20 misted into the combustion

chamber.

If you have no valve, the droplets of oil = will only=20 produce an oil sweat at

the exit in the rotor housing and not doing = anything.=20 Sorry!

 

This is = very=20 interesting.  It is the first time I have seen an explanation of = the=20 valves, and it makes sense.  When I got my engine from Atkins, he = said to=20 simple cut off those valves at the injection ports, and block the = holes.=20
