Hello all,
1st year as a Doo owner, and I yet again come tapping the knowledge on this board. At start up my 01 700 Twin will idle up to abt 3000RPMs and as I drop the choke she'll idle down to 1200ish. When riding and comming to a stop the idle will "hang" at 3000, and then slowly step down to 1200-1500. When I say slowly I mean abt 30-60 seconds. Is this normal? It seems it hangs expecting to get going so when you grab the throttle the engagement is quick, but again 1st year w/ this sled, so any input, advice as always would be greatly appreciated. Happy & Safe Sledding to all!

my 02 700 does the same and it always did. it takes about 10 to 15 sec to idle down. if you dont let it idle down before hitting the kill switch. the next time you start it, the engine will backfire

your cold start sounds about normal, the hot idle hang is ok but your's is just a tad longer than what i'd live with (5-10sec). Turn your idle fuel mix screws out a 1/4 turn (richer) and go riding again and see how she acts. Idle speed looks about right so don't mess with that.

Can you tell me where on the carbs that screw is? Is there 1 for both or do both carbs have thier own? Thanks for the tip. Were heading out tomorrow afternoon, so if you can tell me where these screw(s) are I can adjust and check it during our ride, and fine tune as needed. Thanks again!

Hey dude! Each of the carbs have their own fuel screw. They are on the right hand side of the carb side facing the reeds/cylinders, they should be adjusted from factory at 1 and a half turns out from seated. You should at least turn them out 2 full turns because they are too lean too begin with. Stock they are 17.5 pilots, too lean and that's why your idle hangs high for so long, change to 20 pilots to fatten it up and the idle will return to the normal 1500 rpm every time and the throttle response will also be pretty close to instantaneous without hesitation.
Just have to turn the screw in or out a little bit to fine tune it.
