2000 XR100 - Completely took my carb apart and forgot to check # of turns my pilot screw. How do I adjust properly? - Is the pilot (slow) jet tapered on the inside (unlike the main jet which seems to have a constant I.D. bore from top to bottom). I was running some wire through either end of the pilot jet to clean out. Each time the wire did not want to go completely through. I could see some light through it and able to blow a bit a air through? Is it clogged or OK? Any help would be appreciated, as I'm going to put back together.
