James, In your reply to the “bogging” thread on the YZ side you said your pump was set one full turn in from “zero clearance.” This made perfect sense when I read it but I became confused as soon as I got home and looked at my carb. A few questions then: By “zero clearance” you mean the point at which the actuating rod begins to protrude below the carb body, make contact with the diaphragm and thus begin to pump fuel? Did you check this with slide fully closed (i.e. idle all the way out)? Either way, how many turns in is your idle screw set from full closed? And finally how does the rod detach from the plastic arm (so I can see if it is dirty or corroded, the action doesn’t seem very smooth)? Thanks!
