85 Ski-doo formula Plus carb adjustment?

According to the Shop Manual for carb adjustment, it says:

1. Turn the idle-speed screw clockwise until it contacts the throttle slide then continue turning two (2) additional turns.
2. Tighten carburetor cover with throttle cable adjuster jam nut unlocked, press the throttle lever against the handle grip.
3. By turning the cable adjuster, adjust the carburetor slide cut away so that it is flush with the top of the carburetor outlet bore.


when I do this, the slides go where they are supposed to go with wide open throttle but when i release the throttle, the slides are higher than the Idle screws and they dont even touch the slides which makes the idle about 3500 rpm's. The slides dont go all the way down when release the throttle because the cable adjuster has moved the slide all the way Up. What is wrong?

I hope that makes sense what I tried to explain.

I use the Shop Manual for Bombardier Snowmobiles.

Don't worry about doing it that way. DO the idle like it says, then adjust the cable adjustment so there is about 1/8" of play in the throttle lever before the slide starts to move.
