      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?

      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.

      Raptor Pre-ignition?? (Maybe)
      By jordan_ATV
      I got a 2005 350 Raptor Special Edition and I'm dealing with a no start issue; the weirdest thing is when I'm cranking it fires and slows down showing signs of pre firing, smoke shoots out the carburetor every time it sparks. every electrical part (CDI, Rectifier, Stator, Coil) has been swapped out from previous owner, the top end of the engines all new and I cleaned the carb out, anyone got any ideas or similar problems, also is it possible to have a bad spark timing

      04 Suzuki Eiger 400 Starting Issues & More
      By alexwv1863
      I'm currently working on an 04 Suzuki Eiger 400 and ran into some issues. Main issue being it's really hard to start. Once I get it started, it runs bad. Sounds like it's missing, which I'm pretty sure is an idle issue. It's not my 4 wheeler. I'm working on it for a buddy. Someone started working on the original carb and 2 jets were missing when I got it to work on.
      So, I ordered a new carb. To get it to run, I had to adjust the throttle screw on the handle bar almost all of the way out. Even doing that, it still sounds like it's bogging down and missing. 
      I did put a gas filter on it, which I'm questioning whether or not that's the issue and it's not getting enough gas like it should. The petcock only has an On, Reserve, and Prime option. It also has 2 ports. I guess I have the hoses hooked up right. There's no way to shut the gas off completely, and also it looks like there's no gas getting thru unless I run it on Prime. Reserve drips gas. I'm going to take it apart today and clean it. I'm also going to take the jets I need out of the new carb and put in the old one. 
      I don't know what all this person did you the 4 wheeler before I got it. There's odds and ends missing that I've noticed so far. What else can I try or look for? What could be the gas issue with the carb and petcock? The carb was completely off the bike except hanging onto the throttle cable. The diagram I found for the carb doesn't help me with hose placements. Any help, or questions would be appreciated. I can attach photos if it would be of help.

      Help! Polaris 2001 325 Magnum Not Running
      By PupATV
      Hey guys! I am new here to the forum and need some help getting my Polaris 325 Magnum 2001 Running.....So I got it for free and it has never run quite right...I put a aftermarket carb on it last year and it was running fine but it only went like 20 maybe 25mph max......But then the needle and seat sealed leaked within a yeah and it flooded it REALLY bad so I changed the oil because it was full of gas. So then I put a genuine Polaris carb on it and I have it set to all the factory specs, but it was still not running right....So I replaced the ignition coil and the spark plug and that solved one of the problems I had (It would bog down and stop running when i would go up a hill) But it still didn't have that much "Punch" to it like my Kawasaki Prairie 300 ans Suzuki Kingkuad 300.....So I replaced the CDI but it's still not running right! It's acting like it rich kinda....So it runs mostly okayish when I have the airfilter on but the top of the airbox off but as soon as I put the airbox lid on it like REALLY bogs down and wants to stall really bad. I have the carb at the factory specs and it has a pretty new fuel pump so I have no ideas whats going wrong! It still nly has a top speed of only about 30-35mph and it sounds like it's choking the whole time! Thank you for sticking to the end, and I hope you guys can help me!
