I got it drilled and tapped but I cant find a good spring anywhere.... I found one from an ink pen but it dosent really put and pressure on the screw... How often will the AP need adjusted after I set it up the first time? Can I just put a little dab of Silicon on the screw so it doset move? Also I am at 155 main and 2 slot for the neddle running at 8k-13k feet. 158 main at 5500 feet... What changes should I make if any after setting the AP?
