Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

I like to put the secondary idle speed screw in upside down, the screw driver slot facing up. Sometimes, on some carbs, this means tapping the hole all the way through from the bottom. I put a dab of silicone on the threads, which allows it to be adjusted, but won't vibrate loose. It is much easier to adjust from the top.
