new member needs Artic Cat Help!!!!


Recommended Posts

HAve 2005 Cat 500. It has been sitting for about 10 weeks, and will not statrt. Cranks good has new battery, but will not fire up. I got all old gas out and put fresh in, but no good. If it has a choke or primer i can not find it. It only has 270 miles on it, so not a lot of expierience with it. Always has some trouble starting cold, but catches eventually, noit this time. Also, small protrusion under carb lesks fuel when running, just idle i think, but not positive. It looks like there should be a hose coming off of it, but dont think so. I cant figure it out. Nearest dealer is 33 miles away. Any help sure would appreciate it!!!!!!

Im not a mechanic, but I am pretty handy and have lots of tools. Is this somthing that someone that is mechanically inclined can do on there own? Are there any reference guides out there to help with instructions on how to? How is the carb mounted?. Thanks to DirtDemon for the info u gave me so far?

Agreed. It does need to be cleaned because you have some dirt under the needle. These carbs are prone to this problem. You'll need some carb cleaner and compressed air. You can do it yourself if you pay very close attention to where the parts go when you put it back together, otherwise I'd recommend taking it to a shop. Also, install an inline filter before you run it again. I had this problem with my 400 before I installed the filter, now it's been years since it's leaked out the overflow.

Also, you'll see a little lever on the side of the carb with a hole in it. That's your primer. If it sits for long periods of time, especially in cold weather give it 3 or 4 pumps before you try to start it.

found primer, but no go. Found line coming from fuel tank where it goes to what i think is fuel filter under seat, then 2 lines go from it to carb. Pulled lines and they were DRY. Had to inject some fuel into line to carb to gwet it to start. Has this happened to anyone before. Once started, it still pours fuel from little nipple(overflow?) under carb though. Is this because carb still need clean. Is round thing under seat with fuel lines to and from a fuel filter? Thanks to all who helped!!!!

Yes, it sounds like the carb still needs to be cleaned. If you are mechanically inclined, you should be able to figure it out if you just dig in and take the carb out. Once you have it out, take it completely apart and clean every part and passage and remove any residue in the carb. Pay special attention to the float stopper and the seat that it sits in, debris in this area is likely the reason that gas is leaking out of the carb.

Yes, that's an overflow drain on the bottom of the carb. You have a piece of junk in there keeping the needle valve from closing when the float level rises to shut the needle valve. When it doesn't shut off the fuel it will overflow from that drain, and run down onto the motor (been there).

Yours is a 2005 you say. Where is your gas tank located? The fuel filter would only have one hose in and one hose out (just a little cylinder with nipples on each end). It sounds like you're describing the fuel pump, provided the tank is under the fender instead of ahead of the seat. This type of fuel pump operates off vacuum impulses to draw gas from the tank to the carb. The ones with the tank ahead of the seat don't need a pump, gravity takes care of it.

      So I decided to pick up a small trailer if I could get one for the right price.  I found this one for a few hundred bucks on Craig’s list.  It is  a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good. 
      I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.  
      I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.

      This is something I'm extremely curious about. Has anyone ever attempted to buy a quad (or any other vehicle) from an impound lot? I've always wondered if this could be a bargain, or a waste of time. Google searches do turn up some helpful results. Looks like the state of NJ holds auctions online which I'd be a bit hesitant about.
       
      My online searches haven't really turned up any results of anyone buying an ATV this way. I'd be really curious if anyone tried this, or knows someone who has. I've actually found a couple pages with online auctions for my state, but none had ATVs.

      Hello folks, my machine wound up with I think water in the tank etc. It runs but speeds up and slows back down randomly. When not running I don't see gas dripping  from the drain nipple on bottom of float bowl and drain screw is closed tight. With normal idle speed I see no leaking. When the idle speed increases quite a bit on it's own, gas appears to start slowly dripping from float bowl drain nipple? I'm wondering if the carb is flooding and the gas is actually coming from higher up and just appears, to be coming out of nipple but, is actually running down the sides of the nipple? I put a kit in the factory Mikuni carb last year after sitting for a while and I think the gas in the jug I used had drawn moisture. I plan to pull the carb tomorrow and clean everything out. I was just curious if anyone else thinks it's probably something in the carb and is, acutally a flooding problem? Thanks Folks! 🙂

      So here where I live in Newfoundland Canada, they let you drive your bike on the road provided it’s registered and insured same goes for crossing highways but on trails you don’t need to be insured. And I don’t even think you need a full license to insure your bike they said it was up to the insurance company. I’m trying to get my old 1985 Suzuki 250 registered they have to do a search for it to make sure it hasn’t been in anyone else’s name first. Hopefully it comes back clean I am pretty excited
