Yeah, and most everyone here doesn't have one. Many of them just go by sound. Not me, I can't do that, so I just go with what works for me!

That's why I gave you the 2 3/4 opening.
If you want to fine tune it, here is the procedure from the manual:
IDLE DROP PROCEDURE
NOTE:
The pilot screw is factory pre-set and no adjustment is necessary unless the pilot screw is replaced. Use a tachometer with graduations of 50 rpm or smaller that will accurately indicate a 50 rpm change.
1. Turn the pilot screw clockwise until it seats lightly, then back it out to the specification given. This is an initial setting prior to the final pilot screw
adjustment.
CAUTION:
Damage to the pilot screw seat will occur if the pilot
screw is tightened against the seat.
INITIAL OPENING: 2-1/4 turns out
2. Warm up the engine to operating temperature. Stop and go riding for 10 minutes is sufficient.
3. Stop the engine and connect a tachometer according to the tachometer manufacturer’s instructions.
(If you really want the tach,
www.rockymountainatvmc.com has an
hour/tachometer for $43.00) Most of the reviews say that the tach is only good for initial setting, but that's exactly what you need it for!

)
4. Start the engine and adjust the idle speed with the throttle stop screw.
IDLE SPEED: 1400 + or - 100 rpm
5. Turn the pilot screw in or out slowly to obtain the highest engine speed.
6. Lightly open the throttle 2 - 3 times, then adjust the idle speed with the throttle stop screw.
7. Turn the pilot screw in gradually until the engine speed drops by 50 rpm.
8. Turn the pilot screw out to the final opening.
FINAL OPENING: 1 turn out
9. Readjust the idle speed with the throttle stop screw.
