 Your four wheeler doing this. I'm going to show you a couple of tricks I want to look for solve the problem All right, so does your sportsman 500 idle good, but once you hit the thrall she wants to die I got that issue with this one and I've been getting quite a few questions on why that is You know it could come down to timing, you know that your valve adjustment That's you know a little far off, but a lot of it stems down to is the carburetor The fuel pump The airlines The air box itself So I already took the air box out And uh On this particular box the little tabs are broken off. So So This lid actually does not seal properly. There's actually a bunch of problems. I've noticed um This hose going to the air box is not correct So you got your vent hose going it should be to the top of the Oil fill which is down here And that hose comes in through the top. It's the breather hose And this is a 96 so this one doesn't have The breather hose coming off the engine and up to the air box This one is in a different spot Normally if you have a newer style one like a 97 98 there's a breather hose coming off the block in the front comes up and there's a There's a filter and then it goes up to the air box So you want to check to make sure there's no cracks in any of those hoses because This vacuum operated carburetor is very temperamental When it's not getting the right air flow You got cracks in your hoses wrong style holes leaks in your air box this particular ATV Was sitting for I don't know six months to a year and when I got it the carb was all gummed up from the gas So I went through and I cleaned it and You know, there's some guys that say yeah, you should just be able to get away with a good cleaning on the carb And that's it I I don't buy into that I I usually get a carbure build kit because you get nice clean jets The fuel is going to flow through a lot smoother than you know older Jet that may look clean, but could be a little crusty So I Decided with this video. I want to show you guys a little trick of what I like to do Um, kind of bypasses the guesswork You know, could it be the carb? In this case, I I think that's the majority of the problem Is this carburetor? Something doesn't seem to be opening closing right if I hit the gas takes off like a rocket But then all of a sudden she's just blah and if I go up a hill it wants to die um a lot of that could be the uh The diaphragm on top of the carburetor here Causing that maybe it's not opening and once again, that's a vacuum issue Um not right about air flow um carburetor even though I cleaned it still could be uh Something minor somewhere that uh that I'm not seeing So I ordered myself a bunch of goodies and uh, this is my Little quick tip of the day You want to bypass all that stuff? Go buy yourself a cheap $37 carburetor off of ebay And uh throw that bad boy in No, these carburetors aren't the greatest. That's uh an aftermarket carb Um, I'm not knocking the product, but uh from what I hear Uh, they only last a year or so and then issues happen. So but I don't know 37 bucks I uh I don't know what's worth more your time or your money. I'd rather throw away 37 bucks Try it out see if it clears up the issue or spend four hours trying to figure it out So that's number one Number two, I got a fuel pump It might not be getting enough fuel as dirty as this is. This was the uh, the one I called the cow in my last video I can't see him either. That uh, that fuel pump is pretty dirty and crusty and who knows what got in there So it may not be pumping alright. It could be a vacuum issue with uh, Not enough fuel pumping into the carburetor Um, and once again back to the airlines the air box um So save yourself a lot of time on headaches Give this shot first you know You probably wasted money on worse things already. So $37 carb find out if uh, it improves power And then you know where to start So and then from there I would replace the vacuum lines um, do those two things and uh, depending how old your 500 is I would uh replace the fuel lines too Only because uh, once they get old they get soft and once again that vacuum from the Fuel pump makes the fuel lines collapse if they're soft Believe it or not, they do and then they pinch off the the amount of fuel going to the carb So what I'm going to do first is I'm going to throw that new cheap carb in See if that cures my problem I'm going to replace the fuel lines and the vacuum lines Put the air box back together and um, I also uh got myself a clean brand new air filter Which will help also But if I can get that air box sealed up nice get my new uh fuel lines and vacuum lines in And put that carburetor in I bet you that's going to cure my problem. You know when I hit the throttle it's not going to die So stay doing it and see if I'm correct. Another quick tip you can try is, uh While you're driving Hit the override button Sometimes this can be an electrical issue And um, say you're going in reverse and what spits and sputters you hit the override button The problem goes away Uh, try hitting it while you're in drive and hold it And see if that improves anything. So if that's your issue it could be An issue with the cdi box Or the uh reverse limiter And that would cause your, uh ATV to spit and sputter and want to die too So keep that in mind. Um, like I said, I'm going to try the cheap carb first See if that uh solves the problem And uh After I replace all the vacuum lines and fuel lines That doesn't work. I'm uh I'm going to go check out some electrical stuff. That crazy override button can cause some problems So there's a way to bypass that So keep that in mind But I'm going to start here first. Start taking that car boat And uh, put the new one in and see what happens. So I like to free up As much stuff and get it out of the way as I can so To loosen up the bolts for the gas tank lift that up a little bit And now I'm loosening the uh The clamp on the boot For the carb. Okay. So another thing to keep in mind Is that carb boot It's to get a little dry rotted And uh, you can get some hairline cracks in there. You might not even see Uh, sometimes you'll be sucking an air through there and that'll lean out the carb causing it to backfire Um, it's a couple tricks you can do. You can leave it run spray a little starting fluid at it or um Um, carb cleaner If it acts like it revs up higher, then you know you gotta leak Um Usually what I like to do is, uh, I'll replace the boot if I can Or if it's something minor, I'll just try to repair the boot But uh, that could be a cause of a backfire issue as well All right, so I've done this so many times. So Kind of forgot to show you viewers. I've probably done it probably a hundred times So I'll take the cover off carburetor And uh, you want to get the throttle cable up So I squeeze the throttle up the handle Now I'm actually doing this The opposite way normally I'd stand be standing on your side grab that grab a little poker The cable up this little Cable stop comes out That's it You can loosen this up. I made a special special wrench It just kind of Took an old wrench and I Packed the sides so I can get that choke cable off That'll fit in there Just give it a turn That way it fits in there. It's easier to suspend it. Here's my uh choke. You get a new choke with the carburetor So use that one pull that out a little spring back Actually get a spring with it too. Oh one carburetor moved. I'm gonna put the new one on All right, it shed a little more light on the subject. So I got this threaded in where it needs to be and Keep in mind you might have to adjust the throttle cable to When you're done with this up on top there's an adjustment. I'm used to doing this from your side. So I'm doing this backwards for me. So It's back We're all getting in place Got my stopper in there. Got the cable behind here. There you go. Got her So I'm gonna go ahead and bump it up just a little bit right away It needs to be and I'll go ahead put the car rod and put the carb back in All right. Got my new carb hooked up I didn't put the air box on yet. I want to see how she responds with all the air box and I'll show you what she does This bad boy out adjustment or there's a small crack in the car boot I think I got a very good shot of this, but I got the carburetor off the boot And what I'm doing is I'm prying up and down on it And right about here. You can't see with my finger in a way When I flex on this I see cracks in the car boot You can see that light So one of my quick fixes is I like to take black electrical tape And wrap it around the carb boot And I'm going to put the car back on and see if She's still sucking air and acting like she wants to quit And so that tells me I have to replace that carb boot But for now just to see if that is the problem. I'm going to put some electrical taper on it Put the carb back on and the clamp clamp her up and see what happens. All right, a little electrical tape to the rescue Got it on that carb boot Hey, this stuff can come in handy So I wrapped it a couple of times are on that I don't know. You guys call it An intake boot. I call it a carb boot But the boot that goes from the carb to the head Had a crack in it Watch this So if you got issues with your carb Or wanted to choke all up You know, like I said, check your fuel lines In this case, it was the carb boot. Yeah, I spent 37 on a carb Uh, I tell you what it improved the power immediately. Um, the old carb. I was actually having a hard time Uh, starting it Let me show you She was pretty crusty Even though I uh cleaned it Uh, I don't know. Like I said, uh, unless you have one of those electronic carb cleaners Um, I don't know. I would check into this by rebuild kit for the carb. But in this case, it was the carb boot so You saw how it was acting before I hit the throttle It would die It would idle beautifully I want to check this out. Like I said, go through everything Fuel lines replace those minor soft um I found that odds, uh My uh vacuum lines They aren't correct. Somebody put them in the wrong Put the wrong type of hose on that's not correct at all and uh Fixed the air box and this bad boy should be good to go Hope this helped you guys all with your carb issues or your uh Your quad uh puking out on you Because I've had a lot of questions on that so I thought I'd shoot this video and and uh Show you guys what to look for So subscribe to my channel hit the bell if you want to have notifications for my new videos I've got tons of videos on uh Polaris ATVs from two strokes to four strokes And like always till next time
