I put my carb back together and have a screw left (probably one loose too). I took it apart again, looked closely, watched 2 disassembly videos from YouTube again, can’t see what I missed.
It’s a 3mm 10mm long, the screw this carb uses to hold lighter-duty parts onto it. It’s dirty like an outside screw (as opposed to the clean screws inside). I’ve inspected the parts schematic and account for all screws on it, except that some carbs of this class use 2 screws to hold the throttle positioner; in one of the videos the guy takes off 2 screws for his throttle positioner. There’s some tiny chance this screw migrated into my stuff, but I can’t think of how.
Anyone have advice?
