I have a 2000 big bear 400 4x4 that i just installed a snorkel on and now the carb. is putting gas out thru the overflow hose on the bottom it quits when i throttle up the engine a lil bit but starts again when it returns to an idle .

It was running just fine before i hooked the snorkel up on it any ideas as to why this is and how to stop it

Your float needle is not seating properly it is a small cylinder with a black rubber tip on the end of it. It is hooked to the floats with a wire loop. When the floats rise up they push the needle float closed and that stops the gasoline coming in from the tank. Sometimes you can tap on the side of the float bowl with a rubber hammer and that will seat the needle float otherwise you are going to have to take the float bowl apart and make sure it is connected properly.

      Need Help with My 2021 Polaris Sportsman – Engine Stalling Issue
      By digrig
      Hey everyone,
      I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
      Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!

      1998 Polaris Magnum 425 starts but dies right away.
      By BillR94
      I picked up this ATV that had no spark. The previous owner said he was driving it and it died and would not start. He discovered it had no spark. He replaced the CDI and the coil with no luck. He got tired of it and I bought it. I replaced the stater and now it has strong spark. Now, it starts for a second or two then dies. It will not stay running. I have checked the timing and it is spot on. The valves are adjusted correctly. I see no warn issues with the cam. I put the original CDI and coil back on it. Same problem exists. Compression is at 65 psi (has decompression mechanism),
      I took off the muffler in case the issue was clogged pipes. No change. I replaced the spark plug. No change. The carb was an aftermarket so I put a Niche carb on with no change. I bypassed the fuel pump and that did nothing to solve the problem. 
      I don't know if this is a carb issue or an ignition issue. I am looking around locally for an OEM carb to try out but not sure that will fix the problem. 
      Can anyone help me solve this problem. I am running out of ideas. 
      Thank you for your time
      Bill

      Is the grizzly 700 engine compatible into any UTV's?
      By Ironworker709
      I have Grizzly 700 that has been pretty much totaled out in a bad accident, but it will still run and drive good...
      Will this engine swap into any of the Yamaha UTV's like thr rhino and Viking 700's?
      Was just going to sell it as is for a engine for someone who needs one pretty cheap..but been thinking about getting a UTV for the family and maybe find one with a blown engine cheap and swap it out
      I already an excellent shape 2001 Big Bear 400 4x4 for us..but kinda been looking for a good used UTV for us and the grandkids on our property to play with
      Not sure of the year..i can't remember what year it was when i picked it up for a buddy a few years ago..he went to jail after he totaled this thing and told me to pick up a few things at his house he was renting and just keep them for myself since he owed me a bunch of money before the landlord sent them to the dump...
      The first picture is when i went and picked it up for him..second is how it is now..frame is all twisted up and plastics are fubarred..going to sell the rims and tires.they stick out way too wide on my Big Bear

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle

      Xplorer 300 Overflow Tube
      By frugalsob
      Hey all, been a while since my last post and can't find anything exactly like I'm experiencing. 
      I have a 1996 Polaris Xplorer 300 and have fuel consistently (based on my opinion) drip from the overflow tube attached to the bottom of the carb. When parked and the fuel petcock turned on, it does not leak. However, once its running, it drips almost 1 drop per second. But only at idle. Once rpm's increase it doesn't drip. 
      I've cleaned the carb, checked the float per service manual, and the rubber needle tip doesn't appear to be worn. 
      Is this dripping normal? I really dont feel it should be. Or, do I need to replace the needle despite how I feel it looks. 
      Any help would be appreciated! 
      Thanks!
