Does it smoke any? If the oil injector is not working, you will over heat and damage the engine quickly. Adjustments are best done by a Polaris mechanic.

You have the Slide needle and the airl screw set properly? Should be middle notch on the E clip, 1.5-2 turns on the air screw, to set the oil pump up, theres 2 lines on the acuator arm of the pump, that the cable hooks too, there will be a line on the pump itself too, the 2 lines are for full open, and close, adjust the cable till they line up, Make sure theres some freeplay in the throttle cable too, not much, make sure the spring on the arm isnt broken either, that will cause it to run full open,,,and load the motor up (possibly why it wont idle)

I know that, that's what I meant. He wants to know if his oil injector is working, if it wasn't, would it smoke? No.
