Hi guys, I have a holley 650 4b carb with electric choke and im always running rich and cant stand buying new plugs every month. I need to know how to adjust my carbs air fuel mixture. I know its something with turning the 2 screws on the front but i want to do it the right way.
Here's a pic of how my plugs look now. I dont want to drive my car anymore, its blowing out a dark grey/blackish smoke
