My ATV only starts when in full choke even after I let it warm up and ride around I try to lower the choke but will end up stalling. I just put seafoam in the gas tank and will try that out first in about 15 min. I'm just worried that when it gets cold I'll have issues. Also, when I try to lower the choke after being warmed up I hear no difference in the idle. Is there a way to adjust this?

Side question, when I do stall and im in gear its hard to go back into neutral to start it up again. I tried rocking back and forth but that didnt work. After 3 min it went into neutral smoothly.

First Welcome to Quad Crazy.

I would check and make sure you have the airbox lid on properly and there are no leaks from there to the carb. Then check the tank and make sure your fuel filter is not plugged or the bottom of the tank. Sometimes on plastic tanks some of the cut plastic can get in the lines and the jets.

The sea foam is great stuff but you really have to run a tank of gas or so before you start seeing the benifits.

Third I would hold off on adjusting the carb until you tried everything else, if it ran fine before then I would just clean the carb and not adjust it. Check the jets and see if they have anything in them.

For your other question, alot of quads have the start in gear feature, try holding the brake (Make sure the brake light comes on) and starting the quad.

      need help on a yamaha raptor 80 stalling
      By Gtc4d
      I recently purchased a raptor 80 for my grandson for  christmas. I am trying to make sure it is running properly. i have rebuilt the carb and adjusted the carb idle then the mixture to middle of where it runs rough and it runs great for about a min or 2. then it stalls out. I can usually choke it and it will start so i feel it is lacking fuel. the fuel shutoff valve has been changed and i checked it for good fuel flow.  any ideas of what to check next. I am planning to vfy fuel float height tomorrow. I visually checked it by turning carb upside down when i had it apart and it looked level. any ideas are appreciated. 
       
      Thanks.

      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

      Choke problems 2000 Suzuki quadrunner 500
      By Jason39
      I’m having a issue with my choke when its on it runs fine when I cut the choke off the atv cuts off went to take the carburetor off and saw the choke plunger broke at the nut to screw it in could this be my issue? Do I just need to buy a plunger kit and put it on? I took the carburetor off and cleaned both jets anyway just to make sure and it’s still having issues staying on
