Your pilot jet in the carb is plugged up or to small you will have to pull the carb out and clean it if you have a wire brush you can use 1 of the needles off it that will fit in the tiny hole in the pilot jet push it through and then spay carb cleaner through it and the main jet put back together and it should run fine

I have 1999 Polaris Sportsman 500. Just replaced the carb, but now it will not start or run. I've adjusted the idle screw, etc. Ideas?


Adjust idle and mixture screws to default positions - start it and then make the necessary adjustments. Idle speed, low and high speed mixture settings if applicable..

Tao-tao 150. It starts and idles fine. When I press on the throttle, why does it die?


A lack of fuel. Obviously the idle/low speed circuit is working inside the carburetor, but the high speed circuit isn't flowing fuel. You need to disassemble the carb and remove the main jet and needle jet and clean the holes in each. Then with some aerosol carb cleaner, blow out all the passageways. If it can get fuel, the motor will accelerate. One final thing to check is the air filter. Clean as necessary.

2008 polaris 500 ho efi keeps cutting out and dying when it is warmed up and going on rough terrain or up hill??


Carburetor could be dirty or fuel filter clogged. Put a container of carburetor cleaner in your gas tank, fill it up, and run at idle for 5 minutes, see if that helps clear up the problem. Carburetor float could be stuck, or choke plate.

2015 Polaris 900 won't start. Was starting with fast idle, rough running with backfires, now won't start at all. Was running perfect.


fast idle start usually indicates an air leak somewhere.check carburettor bolts are tight and engine head bolts are tight.try that first

I have a Kymco Mongoose 90 that will not idle when the motor is warmed up.


does it idle up and down at will,,,, and gets worse when hot? (if yes - the valves are too tight!!) maybe a little hard to start...??

The carb may need a professional cleaning!

Wont shift from nutral in to gear while running


Often, it mean that the clutch stay engage.
Now the question can be, is the idle to high for the clutch to disengage while at idle? you might try to reduce the idle speed by turning eather the nob on carburator or the ajustement on the cable.

then if the idle is very low and the clutch still engage (that is why you can not shift) you migh want to check at the clutch and see if it is not stuck.

Arctic cat 500 dies when you give it gas but idles fine!


You still have a carb issue, doesnt take much trash to chock it out when giving throttle. if you done the carb clean twice, try seafoam, does pretty good at cleaning the carbon out. use it as directed while running. it will smoke bad while preforming this proceedure so dont panic whens it smokes the neighborhood out.

I got a 95 big bear and i got a problem with a rough idle and back fires


If it's been sitting around for a while it could be the idle jet has a little craip in it (it don't take much) but if it's spitting fuel out then I would make sure the float levels aren't sticking.

Atv hanging idle


check your float height? sounds like its high and runs normal when cold like the choke is on but when warm its getting too much fuel.

I have a 125 eton 4wheeler.it starts right up but runs out of gas.I tried to clean the tank petcock filter,but it was clean,so i put fresh gas in.Still the same thing,runs,but take off and it dies.I also...


Does it die as you twist the throttle or after riding it a short distance? I know its seems a silly suggestion but are you turning the petcock in the correct direction? Try the twister in all of the setting positions and see if a different one fixes the problem. Keep in mind if it dies on a throttle twist it might not be fuel causing the problem.
