Rebuilding my Q-jet on my new truck. I can’t find any videos telling me what this screw is. It has a spring under it so I’m assuming it’s an adjustment of some sort. Every video of Q-jet rebuild shows a carb that doesn’t even have this at all. Maybe a truck specific thing? This is a stock carb original to my ‘76 gmc K25. Thanks!
