all winter the quad has started and idled right around 1100 RPM since we had over 70 degree weather yesterday and last couple days I noticed when I start it it cranks hard (almost as though its starving for gas or starting to flood out) if I try and "blip" the throttle it clunks and loose all power have to turn key off and back on a couple times to get it to turn over again and when it starts its only idling about 950 RPM. is this something as simple as a carb adjustment or is it something else that I need to look at???

it is a carb on it I run it enough to put about a tank of gas through it each month even over the winter so I dont add any preservatives to it if it sat more than a week without running it I would add stabil to it but it dont sit that long battery is good I use a battery tender all the time I was thinking about changing the plug this weekend in it and change the oil to get ready for this summer to me its strange that colder weather it started and ran fine as soon as the weather warmed up it started acting up

GGGRRRRRRR!!!!! just found my problem the retainer spring for the throttle adjuster is broke again and bouncing on the starter again so time to break out the zip ties and get it back up again this is the 2nd retainer spring I have put on it so I am done paying to have a new one put on just to break again

That's why I like the old BST34 carb with the straight idle adjuster instead of the BST40 with the curved wire idle adjuster! They would break the wire spring holder on the carb bottom,people would either zip tie em up or not notice and wonder why the idle kept changing! Plus they have a habit of corroding up and stripping if you don't take the carb side cover off and keep em lubed up every now and then. Ain't cheap what Polaris wants for these if you lose them either! Glad you found the main problem! OPT

well I wrapped a zip tie around the adjuster put another one through it and up to the spring and zipped them together nice and tight adjusted the idle to 1100 RPM and its starting like new again. one thing I noticed and will get a new one was the pre filter had a coating of like carbon on it so took it off and washed it good until I can get one this weekend which I am assuming thats because of the idle being out of whack

durring summer when I put MILES and MILES on it I clean or replace every 2 weeks over winter I put about 160 miles on it over the winter so I didnt mess with the air filter that much with lower ride times. when I pulled it off and shook it it was almost like I stuck my hand up a chimney all black and sooty took the pre filter in washed with warm water and dawn let it air dry as I zip tied the adjuster and reinstalled it

My curved wire adjuster broke off 4 years ago. When I take the the side cover off I can just fit my hand on the idle screw to turn it now. I fool with in about once ever few months ,I guess the motor vibration knocks the idle setting out after awhile and always to a lower rpm.
I might take the idle screw out put some "loctite" and set the idle up once and for all. LOL
