i have a 1992 arctic cat prowler 440 that will not idle unless you are touching the throttle. you dont have to hold it open just a light touch but when you let off it's like the sled shuts down. the lights turn off and it dies. i thought it was the cables but ajusting them did nothing. the sled runs great but just wont idle. any ideas would be great

Little white washers under the throtle lever!

Try adjusting the idle up a little bit. That is all I can think of sorry!

There's an idle screw and an air screw to fool around with your idle. Of course, a carb cleaning could help too. Since it needs some throttle to keep it running, that's an indication that you're getting too little of one or the other. Could be a clog, could be an adjustment. Either way, go to the carbs!

it doesnt seem like a carb problem. the jets are all new the carbs were soaked and cleaned ,new fuel lines . it runs great and will idle but you have to be touching the throttle

Then it's an adjustment. The gas flow at idle is controlled by the screw on the side opposite of the clutch (phillips) and the air at idle is controlled by the screw either next to it or on the opposite side depending on which version of the roundslide you have (flat).

When the throttle lever is released is there at least 30mm (1/8") of slack at the throttle block?
If the cables are set too tight, it is hitting the TSS and that is what is shutting it down.

there is a small amount of slack in the cable about 2-3 mm but when u touch the throttle to remove the slack thats when it stays running. could it have something to do with the sensor screwed to the side of the carb? is there a way to turn off this sensor

That's the TSS and it can be easily bypassed. There's a how-to video on this site made by Blaine1.
