These screw into the top of the needle & seat. Used to hold the needle and seat in place. Loosen the screw, adjust the needle & seat using the nut, then tighten the screw back down.

Great parts, quality business
Quality parts, that fit and work properly. Great to have Mike's carbuator parts to get hard to find and get all kinds of carbuator parts! Great job!
Great carb kits, these guys are pros. Order with confidence.
Nice to be able to get this part individually and at a great price. Over the years the screw gets overused. Brand new is the way to go. Or get one as a spare..
Quick deliver parts worked great
