Your question came through [to me] clearly, but it isn't "useful" to try and answer exactly what you asked. Here's some info that will likely give you what you need, but is not necessarily in response to your actual question...
Adjustment of the the carb slides is achieved as follows: Pin the throttle wide open and look into the inlet side of the carb. At that point, the leading edge of the main slide should be *just* higher than that of the carb opening. Once you've adjusted the cable for the slide to be in this position at WOT, the slides are adjusted correctly. From there, the slides will be in the same position all the way down to idle.
It's important to be sure that the cables are connected to the slides correctly - so, double-check this inside of the carb body before you start.
Adjustment of the choke plungers may or may not be necessary. Here's an easy test to do:
Use a thin gauge solid wire and bend it at ninety degrees about 1" from the end. Put the choke on full and insert the tip of the wire into the opening that goes from the carb body toward the plunger. Once the wire is fully inserted, flip the choke handle to "off." At this point, you should not be able to easily pull the wire out of the opening because the plunger would be resting on it.
Apply pressure to the choke lever as if you were going to apply the choke. You should be able to apply some pressure to move the cable a slight amount and the wire should then easily slip out of the opening.
Repeat this check for all plungers / carbs. If your results are different from what I described, adjust the plungers until you get the results you need.
Adjusting the plungers is as follows:
There's a jamb nut on the top of the plunger section. Loosen it. If the plunger is in "too far" (doesn't lift out as soon as it should), unscrew the plunger. If it doesn't seat correctly (you can slip the wire out with the choke off), screw it in. Once you have the plunger adjusted to yield the results of testing above, tighten the jamb nut.
Idle anywhere from 1500 to 2000 is fine, and many sleds seem to fall in the 1600-1800 area. 1900-2000 for yours is fine.
I *believe* the cutaway number is a measurement of how much "play" there should be in the throttle control itself before it begins to move the slides.
