Have you checked the fuel flow from the tank ? Sometimes the petcock has a screen or a blockage that does not allow the fuel to flow freely.  Also the air/fuel screw, was it put back in properly? I’ve seen people put the washer in before the o ring etc. So be sure it’s back in the right way. 

Second is the bowl and fill pin working and set correctly. It might be set to low and closes off fuel to the carburetor prematurely. 

Lastly I always recommend sending in a small piece of wire through the ports on the carb. Sometimes air just isn’t enough to clear out a tiny hole like that and the final adjustment. Air fuel adjustment set point? What did you set it at and have you tried to adjust it while the bikes running?

      So.. it a weird one.. The quad surges as you go down the road. By the looks of my tracks, it's one wheel only. High range, low range, 2 wd , 4 wd.. It just doesn't matter.. 
      You can see in the pictures the marks it leaves. That was in a straight line, with hardly any acceleration. 
      Any ideas?

      I'm looking for a repair manual that's specifically for a 2016 Arctic Cat 500. I have looked in the downloads section and there's one but it's for 500,700 & 1000 models. When looking through it, things I'm trying to find to fix on my 500 is not specific for just that model, and it's geared more towards the 700 model. So, needless to say, it really isn't helping me. I really hope someone out there has one. Thanks.

      Okay, so I have a 2002 Rubicon 500…bought it last year and it sat for several months until I put a new rear axle in, FINALLY got that done and was super excited to finally have my wheeler going, just to notice a strong gas odor. Popped the seat off and sure enough, pouring gas from the carb overflow. Fast forward a few more weeks and get the new carb and get it in, no leak! Yay. Except now I have no spark. 😒 I’ve tried another plug and checked and am getting no power to the coil pack. I’ve read and read and mostly what I’ve found is ECU, which is fine…but I like to exhaust all avenues before buying the more expensive parts just because I don’t wanna spend the money and it have ended up being something simple that I overlooked because I was trying to rush. 😂 I don’t know if it’s relevant, but I read on another post that someone had similar issues with theirs and it was the sensor on the side of the carb, just a thought since this literally happened after I put the new carb on. It also displays “- -“ on the display screen where it should show the gear position.

      Hello,
      I have a 2022 Honda Rubicon and I have an issue where it won’t start, when I turn the key for power nothing lights up and it won’t start but the lights will turn on with the light switch, I’ve checked all fuses and they’re good, I don’t have a wiring schematic I’m not sure where to start, I checked the ignition fuse when I turn the key on and there’s no voltage there, I used a jumper wire from the batter to the top of the ignition fuse and then it works fine and starts fine but as soon as I turn the quad/key off it won’t start again until I jump the ignition fuse with battery power, just wondering if anyone could give me some tips where to go with this or if anyone has had the same issue, thank you.

      2000 Suzuki will not fire. Fresh fuel, new plug, has 170 pounds of compression, super hot blue spark, won't even fire if you put fuel directly into the spark plug hole. Carburetor has been cleaned. Any ideas? Thank you...
