I've started another topic because I've created another issue. Though someone may know how to do this properly. I was playing around with my idle and mixer screw on my carby today as I've messed things up in the past. I'm not 100% sure what I'm doing. I have a small bump at low RPMs, and I think I created it by messing with these screws. I realize this could be a myriad of things but I'd like to focus on this for now.
On my 4KC carburetor there are three screws. A Fast Idle Screw andIdle Speed Screw and a Mixer Screw. (Photo below, couldn't find a better diagram).
How do I coordinate the adjustment of these three screws to set these correctly. Where should the idle be when setting the mixer screw for example? What do I do with the Fast Idle Screw? etc. etc.
