Thats the one. The other screw in the other side (smaller one) is the air screw.

You will have to take the airbox off to adjust or get a long set of needlenose pliers and see if you can turn it without. Its a good idea to pop the airbox off and sync the carbs at the same time to confirm both opening and closing at the same time. Idle can be adjusted at the same time.

can you adjust the idle with the airbox removed and sled running? just wondering if idle will change when airbox reinstalled ...thanx

IMO the best way to adjust the idle is to back those idle screws out so they are not touching the slides ( don't even use them) , then use the cable adjustment to sync and adjust idle. This way both slides will leave idle at the same time and always be in sync.
