Would somebody out there who is more knowledgeable than me please educate me on the operation of this pump?
 
There is a plunger controlled by a stepper motor. Then there is the thingy that spins. Then there is some other thingy that moves in and out.
 
Which thingy does the pumping and which position is max oil flow. Plunger in (towards the motor) or plunger out (away from the motor) my plan is to just fix it in the max oil setting and use 2 cycle oil. Or perhaps use a set screw to adjust it until the oil flow/fuel flow is the same as you guys running premix. I will be replacing the nylon crap with hard lines.

P.S. Thingy is a technical term. If you prefer substitute dumaflatchie or thingamabob.
