tillotson 1A carb A-22

As I try to adjust this carb, the neddle valve on the bottom controls the amount of gas that leaves the bowl. What does the spring loaded screw above the bowl cover adjust? Nice carb, not many adjustments....thanks Bob

Hi Bob,

That should be the Idle or low speed adjustment...The operators manual refers to it as the secondary nozzle and it is screwed in to make a richer mixture and out for leaner mixture, backwards as you might think...Hope this helps...Bill
