I was just looking at where the throttle cable attaches to the plate on the side of the carburetor and I'm wondering if I need to readjust that. I noticed while I was adjusting the idle/ throttle adjusting screw that it wasn't able to go back to home position unless I put pressure on it with my finger. The engine actually sounded better when I did. I was thinking that maybe the throttle cable was too tight. Could I be on the right path? I will also look into your suggestion as well. I am an amateur at best. Learning as I go.
