wont start

[mrfarinhight]

hey guys this warrior isn't mine but i'm helping fix it. anyways a while back it would crank but not start and i found it was partly the stator and part because it had a bunch of **** sitting in the fuel lines. well i fixed all of that, rode it about 3 times and then it sat for about 6 months. well, now the same thing is happening again, but i think the carb is all junked up...specifically the jets. i know its not the fuel line because i had a filter put on to it. what i need to know from you guys is how do you take off, and properly clean the jets and the rest of the carb. i've never done any carb work before this is the first time i've had to so a little help would be appriciated

Im interested in his subject as well. the whole carb clean thing

 

[yamarider]

There's really not much to say. Just take it apart and spray carb cleaner in all the orifices and passages, paying most of the attention to the pilot jet and main jet. Then put it back together the same way it came apart.

Ok well its been a while and i fainally got all of the work i needed done and have time to work on the bike. what are the stock screw settings for all of the jets? i checked an online manual but all i found was that i think it said pilot jet needs 2 turns out?

i use tip cleaners 4 torches to clean jets and then berkebile 2+2 gumcutter to clean with its the best **** ive ever used, yea i think 2 or 2 1/2 i dno just adjust while u try to run it and find out what works best that what i do i dial them in myself turns out better anyway...and you could always do a plug chop and see how your running afterwards

o and btw lol i hate warriors carbs there the biggest pieces of junk with a sorry excuse of an accelerator pump it seems they have to be almost flawless condition to work well...ill be glad when i get a z-400 carb setup or rappy 350 1 at least or maybe ill hit the lottery and get the edelbrock...ha

 

[mrfarinhight]

oh **** thats not good. you said they have to be in flawless condition to work. its not my bike i have no idea where the jets are located on it but i've taken the bottom of the carb off and cleaned it out (it had a big chunk of gunk completely stuck at the very bottom..i used a straw to scrape it off and it left a few marks on the carb, not sure if thats bad or not, and then blew it out and washed with gas). as for the top part of the carb where the majority of it is located, i cannot reach anything in there so i just blew it out with compressed air. after all that it is still not working so i'm thinking i have to take the whole carb out and completely clean it out because this carb has not been touched for roughly 10 years. and the problem with the jets is the bike has not started for at least a year so if i change the jets i'm not sure i'll be able to start it. also after i cleaned it i sprayed some starting fluid into the air box and tried to start it. it will start for about 2 seconds running very bad and then quit. for some reason it is not getting gas

so....after all the **** i just said, do you think the reason it is not getting gas is because of the jets? or somewhere in the carb area? and its not the spark that was fixed a few weeks before it stopped running.

haha also i should mention i am having a very hard time finding the jets in this carb so a specific location would help very much

You don't ever use a torch tip cleaner on a brass jet. You will cause many problems as you will ruin every jet in the carb.
If you take a piece of copper muli stranded wire and only use the required amount to fit through the hole and properly clean the jet it works. Also carb cleaner and some air pressure. Don't use this on any diaphram carb though as you might rip the diaphram with all the air pressure.

well i was going to take the whole carb out and clean it but then i'll have to take all the plastics in front and gas tank out but i didnt have enough time so i just took the bowl off of the bottom and tried again. i took out 2 little brass screws that had a flathead slot on them. i'm pretty sure these were the jets, one has a pointed tip and the other central one(one with plastic disk around it) has nothing but a hole in it. well i took them out and washed them in gasoline, they were a little dirty, and blew out the holes they were in. but it still doesnt want to start. when i used starting fluid, it starts and runs for about 2 secs, releasing only smoke from the exhaust. i really have no idea what to do now except take out the entire carb but i dont have much time to do that.

 

[blonka]

You dont hafto take the plastics off to get the carb off its realey easy. To tell if your geting gas or not is to turn your engine over a few times then pull your plug if its wet your geting gas if its dry your not. A good way to get a stuborn engine to run evin if its realy low on compresion is to tie it behind a truck or another fourwheeler and keep trying to coast start it.
I hope some of this helps.

lol...theres nothing wrong with using a tip cleaner as long as ur carefull and you dont use a big size...thats just to make sure u get all the gunk or anything out and berkebile 2+2 gumcutter has alot of air pressure in the can actually thats why they work well, but stay away from the rubber parts,gaskets cuz it will ruin them...but it sounds like you need to break that carb down and carefully clean everything and set your fuelbowl height,and make sure your needle valve on ur float and stuff is ok if the float isnt set right from being gunked up then that will starve your self of fuel,and you dont know what your needle is set at im guessing? most likely you wouldnt have to deal with that

Yes there is and even if you use the correct tip diameter you still take material away from the brass jet causing it to loose it's factory tolance that it was calibrated at.
If you are using a cleaner that wreaks the rubber parts of the carb then you are using the wrong cleaner.

hmm well i'll explain to you guys what i found. the first jet i took off was the one in between the floats. its a little brass screw with no needle on it. and the hole is completely open. before i took it off i was going to check how far out it was turned, but it was already as tight as it could get. not sure if that is how that jet should be. but anyways the other little brass screw(jet) was the one behind the first one. (a little help on which is pilot and which is main would be great, i assume one between floats is main.) so i took this other one out and it does have a small needle on the tip of it, and the bottom was covered in clean grease for some reason. then the needle tip had some black on it which i cleaned off. now, on this needle it looks to me like there is a hole in the top of it. but i cant see ****. it is either supposed to look like a hole but is filled, or it is supposed to have a hole in the top that you can see about down to the middle. this needle has junk in it all the way to the top. i have no idea if this could be an issue or not. by the way i tried starting a few times then pulled the plug it was completely clean and dry. and if you can take the carb out without taking plastics off, PLEASE tell me how because i will most likely never take it out if it involves plastics.

i would love to clean the entire carb but i cant get it out. the only reason i cant is because of the throttle cable. and to get this out you need to remove the black cover, and one of its screws is behind the frame. so i cant remove cable, and cant remove carb.

alright the bigger jet the sits up higher and is where the needle goes through is the main jet that needs to be clean cleran no dirt in any holes the other smaller jet is the pilot,any passages or holes in that carb you should get a carb cleaner with the straw and spray it through...now when you say needle...you mean jet? the tip of the jet or the actual needle cuz the needle is suppose to move up and down inside the main...that needle is solid,but the jets need to be free of dirt on both sides...you really need to just pull the carb off its pretty easy actually...you can take those two bolts off that go into your rubber intake and loosen the air boot clamp behind carband just pull it out a little lean it to the side so you can get that black cover off then take cable off...then if you want theres 4 bolts 10mm prolly to take the gfas tank off then you can pull that carb off...its gonna be really hard to clean that carb right unless you take it off...so your best bet really is to get that thing off there...then it will be easier to acces everything and see what your dealing with

 

[mrfarinhight]

it doesnt matter what carb cleaner is best i dont use it anyways i use a cup full of gasoline. i never thought about removing all the other bolts then lowering it down to take off remaining cover bolts, i'll try doing that and getting the carb out. since i havent taken the whole thing out, i have no idea whats inside the holes. all i can see is the brass screws i took out. one of the screws has nothign but a hole in it, i assume the jet is up inside of the hole it came from, and the other one is longer and it has a needle like thing (it comes to a point, but with a hole in it). i'm going to just try and take the whole thing out now and poke a hole through the needle see if anything falls out and dump some gasoline in the carb.

You should be able to see take out the main jet in the middle that connects to the jet needle tube. Take out the pilot jet and fuel screw. Also remove the float assembly. Basically biggest things on the carb that will effect fuel flow.
I would also try and get the side cover off just to make sure the low speed air jet is ok and free of dirt.
Clean these parts throughly and you should be ok.

 

[mrfarinhight]

ok well i got the carb off finally and took a little look at it. its getting late here so i didnt have much time so i'll look in detail tomorrow. but i unscrewed the 145 jet (i think thats main, in between floats) and there is nothing connected to the brass screw. but if i look inside of the jet tube, or the hole it came out of, i can see a very small circular piece of metal that (about the size of a needle, possibly the jet needle?) and it moves around in there. i am not sure if that is supposed to be stuck in there but it is stuck. i tried using some things to pull it out of there but it is pretty stuck in there. please let me know as soon as possible if that needle is supposed to be stuck inside of the hole, or connected to the brass screw. i could take the float off too but i dont really know how to re-set that.

and question #2 is, what is the low speed air jet?

 

[jasonp]

yea this guy is smart and everything but he seems like he is cocky with his knowledge and seems one sided with things maybe he just has experience with atvs and motorcylces if you have experience on all mech things you will few things better and easier...lol but yea funny funny hes only one ive had to place a freaking arguement with...lol he is saying not to use carb cleaner on a carb LMFAO

LMFAOFOFLHFSMFLOL
I am saying don't use a carb cleaner that will ruin o-rings, because obvously it isn't very good product if it does so. DUH. How hard is that to figure out? I work for a company that is the biggest player in the farm industry, I've also worked for other fourwheeler dealships. They all send there techs to school to be tought the correct way of fixing something.

 

[jasonp]

low speed air jet is on the side of the carb with 3 screws. I believe to be the opsite side of the throttle cable.
Move the throttle and see if the needle moves, it should move up out of the jet needle or main jet holder. It is ment to be stuck to the slide assembly.

the low speed air jet controls mixture or air flow to the pilot jet block circuit on the carb. Basically what happens when you shut the throttle off on this carb and your de-acclerating from top rpm, you don't want the engine to be poping and backfiring so they control that mixture with this jet.

yea i was a mechanic at Martinsburg Motorsports which is a suzuki and yamaha dealer...but some1 back me up on this...lol any1 else know bout this subject...lol cuz its ridiculus, any carb cleaner shud not be SAFE to use on rubber...its not meant to clean rubber and diaphrams and such thats not the purpose of a carb cleaner it deals with metals surfaces...not farking rubber pieces its not hard to farking pay attention 2 wut ur doing and just make sure u dunt farking soak a rubber piece in cleaner cuz what happends is it will dry it up a little and then the size of it gets stretched out...it doesnt like vaporize them lol just be carefull i wouldnt wanna get any carb cleaner soaked all over a rubber,gasket,diaphram piece,and yea that needle shud not be stuck,or jammed at all but it should be able to freely move up and down inside the bottom of that main jet if you find more time later dude just pull that carb off it will be easier you can set it on a table and just examine, take apart and clean everything to make sure everything is able to flow air and fuel correctly, if a carb is correctly cleaned thoroughly and the parts are placed at correct spec and intact right it should work...try to find a picture of one online that breaks down the parts, a manual or something just so you know what all is there and what its called
