The float is sticking. Sometimes a gentile tap on the carb will fix the issue. If that fails try shutting the fuel off until it runs out of gas, then turn fuel back on. If this fails, removal and cleaning carb is required.

2006 Hawkeye sputters at full throtle. Take air boot and air cleaner off runs fine. put just air boot on it starts to sputter at full throtle. Not even the air cleaner just tube from carb to air clean

that might be the overflow tube and should not be hooked to anything, it's like a emergency drain for the carb and when you hooked it to the filter is pulling gas out of the carb at high motor speeds causing it to sputter .. jay

Hello, we have a polaris (2006) 500 sportsman ho..while riding today, unit stopped. looked at rubber fuel line that has an opening (or valve?) that had fuel coming this a broken valve?? RJ

If it is a rubber hose coming from the bottom of the carburetor it is the overflow. If that's the case the needle & seat in the carburetor is bad or has something blocking it from closing. This will allow too much fuel into the carburetor and flood the atv as well as leak out of the overflow. If it is the main fuel supply line from the tank, it will go into a fuel valve located on the left side of the machine (on, reserve, and off). If it is leaking from that hose it can be fixed with a new hose. Let me know if this helps or if you have any other questions, Daniel.

I need to remove the carb and clean it on 450 sportsman how do u remove the throttle and choke cables, also the float needs adjusting the carb drips gas all the time.

if there is fuel coming out of the overflow line on carby you will more than likely have a worn needle and seat and maybe dirt in there, i would not touch the floats, make sure there is no fluid inside the floats (fairly rare)!! check with service manual for cable removal to be on the safe side

I have a 2004 polaris sportsman 90 atv that leaks fuel

it does sound like the float adjustment is off inside the carb. allowing fuel to overflow the bowl and seep out the carb. if you take the carbeurator off the bike and take it to the dealer they shouldn't charge you too much just to adjust it out for you.
