I'm not familiar with pollen but Intek is a brigs and Stratton motor. Without seeing it I'm guessing the dial is a fuel shut off valve. Since you made no mention of a primer bulb (which I'd except it to have) I'd say move the slide to wide open .If its not been used in a long period of time a coke bottel cap of gas poured into the top of the carb should get it to run. I'm not a mechanic so others will add more. This is what I do in the spring after storage of my equipment.
