idle adjustment

[RedFisher]

Hi all,

I cleaned the 4 carbs on my 2004 RX Warrior. One of the pilot jets was definitely clogged. I also adjusted the pilot screws to 2 turns out from seated, as they were all turned out too far.

After reassembling everything, the idle was too high (2200'ish), so I adjusted the idle screw however the idle will not go below 1600 RPM. The screw will not turn CCW anymore. The service manual states idle RPM of 1350-1450, and info on this forum states to set the idle at about 1500 RPM as well. Is there a reason why I can't turn the idle screw further? ...do i need to adjust a cable or is there another problem? ...or should I just be satisfied with 1600 RPMs?

I think all is well now. I just started it up again was able to freely adjust the idle with the idle screw. I set it just below 1500 and the throttle response seems good. Not sure why I had the problem earlier. Did working on a snowmobile in summer heat play a part?

No, but you might want to check/confirm your throttle cable free play as its possible you had the handle bars slightly turned when initially setting the idle where if not sufficient free play in your throttle lever, caused the RPMs to rise and not allow you to get below 1600.

Yes, very likely what I did. Thanks!
