Hi all,
Please excuse my sometimes bad english, as I'm living in, and are a Norwegian native :-)
I own a Polaris Magnum 325 4x4, 2000 mod.
I just discovered that my carburetor flooded with fuel, as the straw from the float body in the carburetor leaked fuel. The engine works now when I'm filling up the carburetor with fuel, using the fuel valve, then shutting off the fuel valve, and driving the carburetor almost empty of fuel.. That means that I' really not using it.

My question is, before I open up and unmount the carburetor, Does anyone have a tip of something I should check around the carburetor before I investigate if there are something with the float parts?

I discovered that the screw (for draining) is completly stuck.. (I bought this Magnum used for one year ago.)

may have bad floats

 

i would say the needle and seat is bad in the carb. this and the floats control how much fuel is in the float bowl at a given time....pretty easy to fix once you get the 4 screws off the bottom of the carb off then you can see it and screw it out....also check to make sure your floats actualy float.....

 

Thanks for quick replys.. I'll check out the floating tomorrow (It's 00:18 AM in Norway now), and give the posting and update.

Yep, sounds like the needle and seat are staying open. Sometimes it can be fixed without buying anything. Take the float out, and the needle. Inspect it closely, and if its just dirty or crusty, take some very fine steel wool, and polish up the mating surfaces of the needle and seat. It doesnt take much crud to hold it open.

 

You've right.. there was a lot of fine "mud" on the needle and also around the whole chamber.. I'll drain the tank to se if there are more alien stuff that whants to come into my carburator... I'll also replace the fuel filter... In my place here, we're often bothered with water in the fuel, but now I can see there are dirt aswell.. Think I'll tank in another place than my regular..

Thank you again for support.

Regards,
Martin

 

The dirt and crud usually comes in the vent, in the gas cap. If you add an inline fuel filter, that should catch the fine particles. If you leave it parked for awhile, drain the float bowl before you do. Its better to dry out the float bowl this way, rather than having it slowly evaporate, and leave behind the deposits.
