Hey everyone new here and also pretty new with a carburetor. I had my carb rebuilt and now i need to adjust it. I found the screw in front and thought that was it i adjusted it to get idle right now its getting to much gas so assuming that was the air/fuel adjustment. So ppl saying to get to the others i need to remove the roll pin. My questing is where is the roll pin and what does it look like. If anybody has a pic or can have detailed instructions that would help a lot. Thanks
