87 lt 4wd Wont idle

Recommended Posts

Hi all,sure hope someone can help. Have a 87 lt 4 wd, started running rich. Flooding after shut down and wouldn't idle. Rebuilt carb,was nice and clean inside. Now it starts fine but will not idle,too lean.will rev fine. Drilled out the pilot jet just to see if that would change things and it will idle,but loads up too much. Also played with the float.Tried different pilot jets but after a few still no good. Have just about given up. Was trying to find one of the after market carbs that will work. My intake side is 30mm. Anyone have any ideas ???? By the way I own a PWC sales and service co and spend a lot of time doing carbs....never had one like this !!

If its still flooding. Check the vacuum tube that operates the fuel pump for fuel in it. Might be a bad seal in the pump.

Are you the original owner? Just wondering if a different model carb found its way in there. There are different jet components for these Mikuni carbs depending on ATV model. You could try raising the needle jet to enrich the mixture.

No Im not,but looks like the rite carb. Did raise the float but no luck.The only thing that made any diff.was drilling out the pilot jet, will idle but loads up. Tried a few stock pilot jets a bit larger but no better....

I was referring to raising the needle jet. I assume you have the type of carb with sliding barrel throttle. Comes out by unscrewing the top cap.

      Working on my oldest son's buddy's 2000 Big Bear.  He was having some power loss at WOT so i thought it worth while to clean the carb and put at kit in it...or at least clean the OEM jets and use the new orings that come in the kit.  It starts and idles like a champ, but dies and wants to backfire with any throttle at all.  I assume lean because it will run decent with the choke on. Air screw adjusted fine, nice crisp idle.  This one has fuel/air screw, low speed jet, mid jet, and main jet.  I was assuming just trash in the low speed circuit so pulled it and cleaned again, still does the same. 
      Two questions I guess:
      1. Does it sound most likely trash in the off idle circuit?  This one has a few more passages and jets than I'm used to...and a darn diaphragm.
      2. It now really wants to leak at the bowl drain screw.  It doesn't seem to tighten enough to completely stop the flow.  Seat looks good, screw was dirty but cleaned up fine with a touch of 2000 grit paper.  First for me.  Any idea here?

      So Id say about 2 years back I bought a 2013 Polaris Sportsman 500 H.O. off of my uncle. It ran perfectly, nothing wrong at all. I usually go mudding with it or just ride trails with buddies. So as you would assume, the quad is quite dirty from sitting for a few weeks.
       
      STUTTERING PROBLEM: I noticed one day out of nowhere that in high gear at 15-20 MPH, I was already maxed out at 4500-5000 RPM  It would get to 15-20 mph, max out on rpms and start sputtering. It sounded like it was basically acting like it couldn’t go any faster than this.
       
      IDLING PROBLEM: I was fucking with the carberator the other day maybe thinking that is causing my sputtering, and now my idle will shoot up to 2600 on start usually, then I will turn the throttle adjustment down to the normal 1400. The rpms with then fluctuate 10-30 rpms back and forth repeatedly, it will then run for about another 30-60 seconds and the RPMs will slowly drop to about 900-1000 RPM and stall out. I replaced the carburetor and everything seems to be working perfect on that, no leaks and what not but it’s still acting strange. Also, I’ve noticed that when looking into the Electronic Throttle Control that two plates that aren’t supposed to touch have to be WAY past touching to even try to fire up. Even when set at a wide open throttle like that, I still have to give it some throttle to get it to fire up.
       
      Here is what I have done so far: 
      Checked the belt and clutch
      Changed out spark plug (Last one was covered in carbon)
      Cleaned the intake and air box
      Replaced the carburetor
      Replaced the inline fuel filter
      Checked that all lines on carburetor are connected into the right spots
      Checked If intake boot was cracked (Not from what I can see)
      Unhooked and reattached new carburetor (About 4-5 times)
      Cleaned battery terminals and battery off
      Shut on and off Gas Line Cutoff Valve
       
       
       
      My next thoughts are that maybe the TPS is fucked up or maybe the Spark Arrestor is plugged with mud. I was thinking tomorrow to purge the exhaust and also check the ohms output on the TPS.
       
      ANY HELP IS GREATLY APPRECIATED. I HAVE BEEN BATTLING THIS FOR WEEK AND REALLY WANT TO GO RIDING. THANK YOU!

      Hi I have a 2000 big bear 400 and i just put a new carburetor on it and it idles fine but when you try to accelerate it sounds like it is going to die, so when it sounds like it is going to die I will give it more throttle then it will go just fine.

      Thought i would share a fix that I came across. I was working on a 99 scambler 500, The customer complaint was that even with the fuel shut off the tank would slowly drain out onto the ground. First I found the fuel shut off was bad/ leaking/ dripping so I installed a new one thinking that would fix it. Then I ran it and and seen that the overflow was flowing fuel out from the bowl. So I cleaned the needle and seat and changed the float height to lower the fuel level in the bowl. Well... It still overflowed and flooded. So I bench tested the needle and seat with a pop off tester. I found that these newer style needle and seats just utilize an o-ring to install the brass seat into the carb.
      The o-ring for the seat had hardened up allowing fuel into the float bowl from under the seat. New o-ring and problems solved.

      I have a Kawasaki  bayou 4WD that started squealing when giving it the gas from a stop. It almost sounds like a fan belt but the dealer replaced the belt about 30 hours ago, so I don't think it is that. As best as I can tell, it actually sounds like it is coming from the front end. Once I am running and moving at a speed, I don't hear the squealing anymore. My first thought was to put fan belt dressing on the fan belt, as a quick test for the problem. It makes the noise when hot or cold.
      Another problem, that started before the dealer changed the fan belt, is that you give the quad a little gas, and nothing, give it more, and nothing, give it more, and it lurches and takes off. The dealer said it needs a new clutch, which I don't buy. less than 400 hours and it needs a clutch? I would say it needs an adjustment. When the quad is cold, as in I just started it for the first time in hours, it does not lurch. It is just fine. It lurches only when it gets hot, as in when you can hear the fan once in a while to cool the oil.
      Any help or insights would be great.

      Does anyone on here have a 2013 honda rancher? I have had several Honda ranchers in the past but I bought this 2013 rancher and it hits the rev limiter at half throttle. It is very annoying and I was wondering if anyone else's Rancher does this. If this is something from the factory or if I have a problem or not just trying to figure it out. Any help would be appreciated

      My 1999 Sportsman 500 since new has had very few issues during the 16+ years I have owned it so it has been a fantastic machine!
      The problem showed up a number of months ago during hunting season and in essence once you start to ride it and then stop, it wants to continue to creep forward and makes it difficult to shift gears and there is a bit of grind when you do.
      Runs fantastic and seem to be no other problems with power to the wheels in 2WD/4WD so the only time you notice it is when you stop and especially if you need to change gears.
      I am looking for a starting point on where the problem could be.
      Appreciate any help!
