I have been rebuilding this ATV for about a week and a half now. I rebuilt the carb, changed the air filter, and cleaned out just about everything I could think to clean. I tried starting it last night and the starter button would not work, so I pulled out the start button and saw that the wires were useless. I finally got to a point where I was able to hot wire it and get the engine to turn. The engine turns, but will not fire. It is clearly a problem with not getting spark or not getting fuel. I just replaced the spark plug and battery. At this point, I am a little stuck as to what approach to take. Im thinking I need to put starter fluid in to see if I can get it to turn over with that and if it does, I need to work on the fuel system.

Has anyone worked on this quad before who has any experience or advice to share? I am an engineering student at Clemson and this is a summer project for me to rebuild an ATV instead of buying a new one. I am ready to learn! Thanks!

If the plug is wet, its getting fuel.

Even if its not getting fuel, not having a spark is the main problem.

You grounded the spark plug and turned the motor over, and there is no spark, correct?

If correct, check the on/off switch and any others. It may have a brake switch. If all that stuff is good, you need to test the coil and stator (generator). You will use a ohm meter. You will need to find out the correct readings.

That will keep you busy. :)

      Looking for Quadrunner Flywheel Starter Clutch Gear race diameter
      By logray
      Hi all, 

      I am wondering if any of you have a Clutch Starter gear from a 1988 era quadrunner 250 sitting around that you could get me a precise measurement of the outer diameter of the race the sprag engages onto, for me? I need to machine a damaged race down and install a hardened sleeve and need that measurement (it's on a different gear than the OEM one, so I can't buy and use a OEM gear).

      99 Bear tracker no neutral or reverse light or start button
      By OldATVowner
      Just getting into this issue really. Been replacing solenoids but now I'd like to track down the problem. This time I'm not getting neutral/reverse lights or start button. Was on a creek ride when it started doing this recently. It cranks by arcing the solenoid and gives me no light or start button but if I crank with the pull cord....the neutral light and the button work. Turn it off and try to crank with the key and nothing. I'm looking into the safety switch issue tomorrow and re charging the battery. Just figured this was odd enough of a problem that you guys might be familiar. Thanks

      oil for air filter?
      By Mikey509
      Hi everyone, first and foremost, I want to thank everyone for all the help I've received. I am so glad I found this community. I also wanna apologize if I'm spamming the forum, I come up with questions as I go, I guess lol. So when I got my Recon, the air box was missing the lid, held together by zip ties, and the filter was ripped and nasty. I have since ordered a new air box assembly. It comes with everything: the box,  lid, and filter ( the insert and the foam), and all the hardware necessary. This is the first time I've seen a metal filter inside a foam filter lol. However, my question is, I have read that you have to oil these filters? Every time I read it, it was always skimmed over, and I could not remember where I had read it. Is there a certain oil needed for this? Is the filter washable and reusable? Do I just stick the filter in oil, lol? Sorry if it sounds like a dumb question. Thanks in advance, y'all!

      Timberwolf 250 starting issue
      By Jdeaton011989
      Hi all. I have a timberwolf 250 2nd that will not start.. I thought it was out of time bc the guy I got it from said it just quit on him. The tensioner had a nut welded to it and it was like2 teeth off. I installed new tensioner and chain and it still will not start. It has fire and it will not hit off brake cleaner. It has compression. Haven't put a gauge but I'm sure it will crank and run with what it has. I double checked my work and it's still in time. Spot on. Both valves move. I'm about to put a feeler gauge on them and I'll cone back but other than that any ideas?

      Starter not staying engaged while cranking
      By HoldenBoy
      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.
