1990 Suzuki Quadrunner 250 2wd; wrong carb?

Hi All,

I have a 250 quadrunner 2wd and the title says 1990 and the vin number checks out right but I got it used and have had it for several years. I'm having fits with the carburator and have the factory service manual but the carb pictured in the book is different from mine and i can't even find a similar model on ebay or anywhere. I bought a kit for it and the float needle is different and that is the main problem I'm having. I can get it started and idling fine then the next day it won't hardly start. It's about to drive me crazy

Hi Buckbilly,

Thanks for your reply. What would be involved in changing over to a different carb? What would do about the throttle and choke cable? Would the set up be the same for a different carb?

thanks again

Here is a link to Ronnies mail order. Ronnie's Mail Order for atv parts, atv tires, snowmobile, watercraft and motorcycle featuring an OEM microfiche parts finder. This carb should be a direct bolt on with no mods. Back in the day alot of people switched out the stock carb for a 230 and 250 quadsport carb because it was bigger. Some dealers done this if it was sold with a snow plow to. Check some other parts sites out to, you might find a better deal on one.

Hi DirtDemon,

Is it possible to get one without buying the whole carb kit? I haven't seen one in a kit like mine as it has a small spring retaining clip at the top of it. I wonder if anyone on line has a schematic of the different carbs and covers the various adjustments. I doublt the specifications in my manuel will be the same.

thanks

Does this look like the right one, you can buy the parts individually at any dealer or online parts supply.

You can get the needle valve and seat set a little cheaper at Babbitsonline.com or at Servicehonda.com and Service Honda has a really clear schematic of the carb. Just use the parts search and look up a 1990 LT-250s.

O.K. gentlemen,

now, I can get it running and ideling great and it will constantly start back up for several hours. The problem now is the next day it won't start again??? It seems as though once it's warm everything is fine but after sitting overnight I'm back in the same boat.

thanks

Hey Dirtdemon,

Man you sure called that one right. I was a little apprehensive about doing the valves but it wasn't as hard as I thought it might be. Anyway, once I adusted both ehaust and intake it fired right up and has been doing great ever since.

thanks a million.

      I just purchased the ATV and it run really rough with the breather filter on and lid on the breather box. Once I take the lid off and remove the filter it runs better but it backfires through the carb.
      What could I do to fix this.
      The carb is fairly new.
      And I put high grade non ethanol gas in it hoping it would help some.

      Out on the trail, visibility is everything. When you’re riding, you need to be able to see every potential obstacle well in advance, and sometimes, that includes things behind or beside your vehicle. On your own private property, sideview and rearview mirrors are a clear value-add, helping you avoid some of the entirely preventable accidents that can pop up when you’re driving in Reverse. On public trails, those mirrors are an absolute necessity, drastically helping mitigate the risk of vehicle-to-vehicle collisions and prevent bodily injuries.

      That’s why Kemimoto, a market leader in the design and manufacture of ATV and UTV accessories, has devoted so much focus to UTV mirrors over the past decade, in addition to accessories like saddlebags, seat bags, whip lights, and more. When the company was founded back in 2011, there weren’t any readily available, affordable off-road mirrors for Side-by-Sides on the market that were much good for anything other than showing riders the rears of their own vehicles. So, the company’s founders took up the challenge, setting out to create their own side mirrors to provide fellow ORV enthusiasts with a better view of their blind spots.

      Mirrors have been Kemimoto’s hottest-selling products ever since.

      Today, Kemimoto has a staggeringly impressive collection of sideview and rearview mirrors for UTVs, ATVs, and bikes on offer, with nearly a hundred unique mirror packages on sale through the official Kemimoto website. Kemimoto makes mirrors to suit any need and any budget. Many of them are best-sellers in their respective categories, and for very good reason: as a direct-to-consumer brand, products are marketed, sold, and delivered to customers directly by Kemimoto. That extra efficiency allows the company to price its ATV and UTV accessories more effectively, and sell high-quality mirrors and other products while keeping prices extremely affordable.
      Equally important, Kemimoto’s ORV mirrors are just plain good. Design, development, and engineering all take place in-house, and the company even holds a few patents for some of its innovations. They have their own laboratory for product testing, to ensure that every mirror that wears the Kemimoto name is tough enough to go the distance. The mirrors are designed for beginners and professionals alike, with ridiculously simple install procedures that typically require a hand tool or two and just a few minutes of your time to set up. They are made to suit the overall aesthetics and performance requirements of the vehicles they are designed for.

      As an example, let’s take a look at a pair of Kemimoto’s lighted side mirrors designed for Sport Side-by-Sides. As the name implies, Kemimoto has built two levels of lighting into each of the side mirrors. You can fire up one or both of the lights in each mirror. And with an angle of illumination of 195 degrees, you can see exactly where you are going.
      Additionally, these mirrors boast shatterproof tempered glass, which helps protect the driver and passengers in case of an impact. They also feature a breakaway design, so they will fold up if you get a little too close to a tree or any other obstacle rather than snap right off. When it comes to construction, Kemimoto made the shell out of a high-quality ABS, while and the frame and bracket are built out of aluminum.
      Of course, Kemimoto is more than just mirrors. The brand also produces and sells its own saddlebags for motorcycles, seat bags for ATVs, backpacks, roll cage cargo organizers, and other storage accessories. They also manufacture high-quality whip lights and mounts, UTV cupholders, dome lights, windshields, vehicle covers, and even some riding gear. But high-quality, fairly priced ORV mirrors will always be the company’s specialty.

      I recently got a great deal on a 2001 Big Bear 400 4x4.it sat in a barn for 2 years while the guy was in college,so it need carb work...got it to use around the property,not racing or anything crazy with it
      It runs GREAT and strong..no smoke or funny noises,just seems to have an issue at times ,when you hit the throttle it want's to die ,most of the time it runs strong.
      So am debating a rebuild kit or new oem carb...i got to looking around really good yesterday and found this broke off..( the bent tube where the pencil is pointing).... is this a part that comes with a new carb?..if not,,where can i get the part?
      I found a diagram online but it does not show the bent tube with a nut on it but says it a "Starter set" in the diagram(Number 21 in the diagram)
      I checked the petcock and it is getting plenty of fuel flow..but it has the common drip leak..so i am ordering a new one,..was going to get the seal kit but for the price it is about the same price as a whole new petcock
      Just trying to figure out where i can get this part for repair

      I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

      I'm fitting a new carb on my King Quad LTF300. From China. Only one I could find in UK. I think it should have 2 vacuum ports.
      The vacuum port for the petcock is silver coloured. I can feel the pulsing vacuum. Putting the tube to the petcock there operates the petcock100% perfectly.
      I can't identify the vacuum port for the fuel pump. The new carb is identical to the old EXCEPT that in what I think is the 2nd old fuel vacuum position is a brass upright port with a very small hole. When running, there is no vacuum I can feel and putting the fuel pump vacuum line there does not give a decent fuel flow - only a small trickle.
      Is this the fuel pump vacuum port - see photo?
      The carb came with a silver coloured screw-ended 1.5 inch long loose port in the box. See photo. Is it intended that you unscrew the brass port somehow and put in the silver one?
      I'd really appreciate your help At the moment I can only do 10mph in a stuttering fashion on the level!

      and put in the silver one?
