Adjustments for the three ends of throttle cable and idler screw in carb

Question edited to add maker.

Remove the throttle body and clean it thoroughly. It is staying open.

Need to adjust the throttle cable by the little nuts in line up by throttle and for idle there should be a screw on side of carb up above the over flo screw (which is on the bottom of the bowl)it will be right above the bowl start it up and turn the screw one way will make it idle up the other way idle down

adjust the throttle to max

If the screw(s) on the carb make no difference... the throttle cable may need to have slack added... IF there is an adjustment at the handlebar... start there and give it slack -- The throttle should be able to move without revving the engine.... if there is not slack or play... adjust the cable until there is.- the next adjustment is at the top of the carb, where the cable goes in -- ....If this does not help, you may have pinched the throttle cable, or have an air leak or the intake valves are too tight-(usually manifest in a "slow to idle" - "run away idle" situation) .....

For the initial settings - 03-12
- lightly seat the pilot all the way to the back - lightly, too much torque and you'll ruin the o-ring in there - then back out the pilot screw 1 & 1/2 turns. From there - you let it run for 10 minutes or so and then adjust the idle to 1,300 +/- 50 rpm - turn your handlebars left and right after adjustment of the throttle lever to make sure it's okay and not binding up - and do your adjustment from the throttle stop screw. According to the specs, once you set that pilot at 1,300 +/- the rest of the adjustment is done with the throttle stop screw. If you do all that and it's still not picking up fuel - definitely give the intake/carb boot a good look over for any cracks or anywhere vacuum could escape - and if it still doesn't pick up the fuel - give the throttle set screw a turn or two. Had a 2000 Yamaha XT225 carb I rebuilt a few weeks ago - adjusted everything as instructed - but it wasn't picking up the fuel. I gave the throttle set screw about a 1/3 turn in to put a little nudge on the throttle and it fired right up. All The Best and Good Luck - Justin Lee, 17 South Industries, LLC

The number 1 problem with ATVs is the carburetor. This could be a mixture problem... too rich will cause backfiring and difficulty starting as the carb needs more air. Try leaning it down a 1/8 turn. The choke is always intended to be used when starting; if you don't need to use the choke, the card is definitely running too rich. If you can't adjust to make it behave properly, then rebuild the carb, It's not difficult.. get a new throttle spring and float too. Ensure you place the keeper clip on the correct groove of the needle valve... where the throttle cable connects. Replace all the jets and gaskets... don;t get them mixed up. One larger jet is the primary jet and the smaller one, is the secondary. Get new screws, if the screws are a bit dog eared. Write down your previous mixture settings and start from there to adjust the mixture for starting and assure a slightly skipped idle. (Don't worry as you add throttle it will run smoothly.)

Does your artic cat have a carb cable if so it will have an adjustment or a clamp on the cable where it attaches to the linkage..check make sure it is set to low idle..and your idle screw is adjusted to low idke..meaning cable adjusted to lowest possible position when the throttle is released..then make your final adjustment using you idle screw..good luck

follow ur throttle cable down to cars there should be a plastic screw close to cable to adjust idea but with polaris that screw can be hard to find with all the plasticc they put in way but if u can see carbs easy enough u will see the idle screw

To ajust the idle there is a nob that you turn that come from the carb,

could be the crank seals.
