Mountain Cat Power Valves

Hey guys I just have a question on the power valves on a 03 mountain cat 900 carb. What kind of symptoms would i see if the power valves were out of adjustment and if i need to replace that gasket if i take them out to clean them. Im looking in my book and it gives me a minimum center and maximum, so does that mean there is a range of measurment that is acceptable?

Second of all when I measured them the adjustment wasn't even close but the sled seems to run fine at high speeds so I'm a little concerned about the measurments on this item.
1.17/1.20/1.24
Those are the measurements for minumum/center/maximum. I get about 1.50 or maybe a little more then that when i measured them. So im a little confused but maybe you guys know something. Any help would be apriciated.

Why wouldn't both adjustments be in the service manual. I'm not exactly sure if mine is an early build or a later build, but i'm leaning on the later build though.

And as far as the gasket i don't know if i want to tamper with that right now, we currently lost our cat dealer so parts are a little hard to come bye. thanks for the info guys I will be messing with this thing tomorrow.

Im running super rich on start up to mid range.
