49cc Carburetor leak solution

- This is a video explaining why your carburetor is leaking and how to stop it with a small adjustment. (for 49cc bikes)
By bending the forks on the carburetor downward (not too much), you can stop the gas leak. If you make this adjustment and the bike does not start, you have bent them too much and gas is not filling the carburetor bowl up enough. You must then bend them upward a little to allow more gas to fill the bowl. To see how much gas the bowl is getting, turn the white gas flow knob sideways to shut off the gas flow. Then unscrew the bowl center screw to allow the gas to pour out. collect this in a container to measure. If little gas pours out, you know the forks are bent too much and there is not enough gas entering the bowl to start the engine. - ยานยนต์และพาหนะ
I must have taken the carb apart 20 times or more trying to understand why fuel was coming out the overflow tube in son's pocket bike. Ordered new carb thought problem would be fixed. STILL leaking from overflow. Was dumbfounded until coming across your video quick 2 minute fix, bent forks a bit and no more leaking 😎 thanks for the video saved alot of people a bunch of time and money 👌
My bicycle motor has same carb. Leaks . Engine fairly new. I bent the part like explained in this video, and it worked! Brake cleaned carb on outside ,test drove. Still drives great, performance not affected. Parked it, no leak found. Even hour later. Btw, I didn't see any other comment saying they tried the fix.
Wow cheers man.I tried this and the gas finally stopped leaking through the overflow!
Good advice but another thing to watch out for is installing the float fork upside down. I did that accidently after cleaning the needle valve and although it ran great and made a ton of power it leaked badly at idle through the overflow tube. And if this fix of your happens to make your engine run rich (read from a previous comment) just put a nitrous kit on it to lean it out. WIN WIN! Cool vid man, keep having fun!
thanks for the tip. Hopefully it will work. Either this or possibly the fuel cut off is the problem. I don't seem to be getting fuel. Then when it's in the off position, fuel runs and I can start her up.
Bloody good video. I have the same problem with mine. very well explained. thank you
This video helped me enormously. Thanks for being so thourough!
Had the same thing happening. Thanks for sharing.
Thanks a lot....its working for me.Ive been cleaning the carb a few time and didnt even think of doing this.So simple.👍👍.
when u get pissed, pound with a hammer smile., wash hands blame a china mann for making crap
Very well explained, thanks for your time
Also if it dont start up you could hold the throttle open all the way and spary some carburetor start up fluid and then you fire it up and it should turn on
Than k you!! I couldn't figure out why the hell gas was running out of this thing.
Thanks for this video , really helped!!
Thank you so much you helped loads
Good vid mate, looks like nearly every carb is set to leak from the factory, judging by the amount of videos & comments about this issue. Cheers
Great video 👍 it really helped me out
Thanks man I need that I had the same problem like that
Thanks mate works like new now
If you are flooding out your carb, youll have an improper mixture going into your combustion chamber and youll basically drown out your plug. It will run way to rich, if you can get it to run at all. Make sure that your intake passage for your fuel is clear and make sure that your float moves very very freely. If it does not move freely, your bowl will stay empty, or it will overflow, both making your engine unable to run, or at least properly.
Iv been trying for days and days with no luck stopping the leak find your video nd bamb sorted
this really helped, thanks :D
Thanks this helped alot
Lol i just got done cleaning my carb out and stared leaking.. i was like i have everything in right wtf now ill try to bend the forks Thaks for the information man!
LMAO ikr
Can you do a video on how to put that pin in properly so it wount come out
i just bent my forks yesterday and it didnt work it still leaks but im going to take it apart again and check the float needle. im still learning about these engines. i work on small engines like push mowers and riding mowers. i dont know what to do if i cant get it to stop leaking, like i said i bent my forks.
This is what i need to do! Thanks
remember , put in drain o it will help ur bowl
Very cool video.
thanks bro for the demo... I learned a lot.
You don't know what you are doing
Mine was leaking like crazy i took the carbrateur apart didn't do anything else put it back togeather and now it stopped leaking ?? Maybe something was just loose or something I don't know but glad I got it fixed
Thanks i love you it works:)
how can you tell when you have done it enough..because im guessing if i over bend it, the the float will cause the valve to close too early without the bowl filling up?
Thanks mate!
Will it harm it if you dont fix the leak? No fires or blow ups is what i mean
i did this and after 10-15mins gas starts to come out of the overflow tube. did i not adjust it correctly? please help!
The flaot has a ridge on top of one side. Which way up should it be..ridge facing down toward bowl or top towards jet
I have the same problem would this be the reason it won't start!
My son has the same carburetor as that. And can't figure out why gas is leaking from the front of the exhaust pipe. Brand new carburetor thanks. Please let me know
If you bend them too down it doesn't allow enough gas in the bowl and the engine stalls after a short while because the gas is consumed faster than it gets in.
Im trying to fix one now and am very inexperienced. Please help with this question. I just put a new line on. That white tube connected to the carborater. Where does the other side of the line connect to? It doesnt just hang freely does it?
This video sure helped me out I liked that
Thank you very muck
would this cause the scooter to not run correctly? my honda spree to lecking from this tube and then its hard to keep it running
Thank you for this video. I had to bend the tabs a good amount to stop the leaking. The ebay seller was no help.
+Dastardly84 Started leaking again. I shook the whole ATV and it stopped. I guess the float got stuck. Now to finally sell this thing.
dont break tabs.. also, once stressed they fail faster..
thats the attitude sell that heep.... ,.
If the carburettor from the scooter two stroke if leaking the scooter can start or not tks
Thanks
what if my air filter is just full of fuel after i have driven but it does not leak any fuel its just full of fuel after a drive. does that mean its ok ?
do we have to drain oil before doing this?
the carby have measurement or it will run lean
Why do some carb likethat have a hole in the chose slide and others not? Shouldnt they have one? Otherwise how is it going to get gas with the choke slide or blocker completely closed.
I've also noticed something new today: the float from the carburetor is not floating straight and it's slightly slanted. When it's in the bowl the float is getting stuck inside because it's not floating properly and wasn't able to rise up with the gas level. So it took me a little bit of work to balance the float, by inserting a small weight (a small nail) to make the float bob in the gas leveled.
Legend!
I need help don't know anything about bikes, bought little orion 49cc 2 stroke,for my 6 year old for Xmas last year,he loved it but was always hard to start then after few days it stopped running,took it to shop they said water in carburetor?Was fine again for a week?Took back to shop (still under warranty) they said guy wasnt there, probably same problem water?wouldn't take it,flogged us girls off,no help☹️ no bike no fun, the neighbor(only guy around i know)checked spark plug, sprayed it with some stuff,it ran for few hours not well,was slow wouldn't rev properly couldn't ride it, tried again few weeks later noticed after finally getting it to start now it's leaking petrol from under this silver thing in the middle of the bike kinda near the motor?Is that the carby?Does it have a gasket at bottom? It's not leaking from hoses but between 2 bits of metal,they sit one above other,one of the pieces is curvy like what corrugated iron looks like, the gas is leaking between there, took back to shop again! Got even more of a run around was told guy that fixs not there, away for while,so tried to get a refund no go manager not there? Then asked if I paid the difference get the 100cc bigger one as advertised, was told none in stock no more coming in!? Getting pretty mad but what could I do? So now I'm stuck with a bike my son has grown out of in the year I've had it, it's been sitting unused for months, im to scared to take it apart probably wouldn't be able to put it back together & i don't have the $ to take it to be fixed, mechanics here want $90+gst just to look at it!? Sucks being a girl that has rip me off across the top of my forhead!! Could someone please take pity be a hero & put up a video of how to fix this,I haven't found a vid that's got the same problem or even the same bike with parts in same place as mine & needs to show everything on what you need to do from start to finish to show how to fix it, it's an Orion japanese 49cc 2 stroke its orange & black there used to be a lot for sale on trade me but I purchased mine from savebarn if someone could please put up a vid if you can understand what the problem is that would be awesome, I'd be forever grateful ☺️☺️😉thank you, I'll keep checking you tube & googling hopefully will find someone may be your video? Much appreciation Law's
What make and model is your quad?
На сколько надо выкрутить винт холостого хода на карбюраторе?
I tryed this but it still leaks! Any help?
i have a coolster 50 max 49cc same carb will that still work with my carb leak and not starting?
joshua harshma
which way does the float go? flat side up or rimmed side up?
flat side up
Thku 🙂👍🏻
If it is still leaking fuel then you either have clean the carb and/or open the fuel screw more.
I need to know what to do when you over fill a scooter gy6 after you run it
Brandon S. Chamberlain take the plug out and crank the engine. it will empty the cylinder out. also remove air filter and check fuel not leaked onto filter.
mine was leaking fuel.. but it stopped when I leaned out the mixture :) no fork bending needed
also it ran alot better leaned then on rich!
That is a different issue
my gas is leaking from my carb right into my airfilter on my taotao 50...i just replaced the carb what is the problem?
rex salyers
Mine is doing the same thing how do you fix it
Mine has been doing the same. I found that the gas shut off valve that is inline between the carb and the gas tank is not shutting off gas flow from the gas tank with the engine off. This valve should allow gas to flow to the carb with the engine running only. I ordered a new valve but until it gets here I just pinch the rubber gas line shut with a small pair of vise grips when I park it.
Can you help please. I notice two pipes. One I originally was the fuel but I was wrong. There are two lines one is fuel what is the other
pile up with sand in carb.. good for it, add draINO
Did this then the pull start broke when I went to test it ffs
Hey mate
Great video 👍
I think I have the same problem
just leaks like drops?
even if I close the fuel line ?
would I have the same problem as you and is it hard to take of the carburetta off ?
thanks
these cheap carbs, 14.95 are horrible... Heard dude say, 'I just got a new carb''.... If bike is not ran every day... the bowl jams.. I just put a new carb on , fine... didnt run bike 3 weeks,,, it happened, float froze.. pain... not sure if im going to adjust it , or buy a new one..
Gas is leaking out of my 50cc scooter air filter, why? Please help me.
Very likely the gas shut off valve is not sealing. This valve should not allow gas to flow from the tank to the carb without the engine running.
Change the whole tube
can any1 help got water in my carb ??
Leesa Maudsley take it of and put it in a tub of petrol worker fir me
Watch my most popular video: "Carb Leaks Gas"
Can't see video
Mine was it was bad
Wait.. a 49cc quad?? I started off with a 450 in 5th grade
Yolki Palki sorry mr “I can ride big bikes”. Biggest looking cock on the comment section
Marc John hahah my friend rides a 250 and 450 but still rips the pocket bikes with me 😂
Which way does the float go back into the bowl ?
i believe ridge side down.
best thing to do is take it apart and set ur parts in order as u take em off and how they come off so u know they go back on the same way. thats what i do
upside down with crown away from u
your fork is installed upside down
same with me lol
dont loose a spring or screw,, also when the gasket is opened, need a new one. put in gasket cement.. upside down
these bikes are crap, had 2 and both leaked when i went to the shop they said when you finish riding don't fiddle with the choke
Unfortunately with this easy fix you can cause the air fuel mixture to run to lean or to rich which can lead to spark plug fowling burning out valves seats and overall poor performance. I have had the same problem with a brand new carburetor with factory float height set incorrectly so just had them replace it :)
this doesnt have valves.....
14.95 ... it crap.
You had it upside down no need to bend it
Can u pls send a picture which side it should be. Plsssss
Android users:
This vide is awful
One thing he didn’t mention is that you don’t want to bend them too much because if you do then it will make the engine not run correctly.
Can you do a video on how to put that pin in properly so it wount come out
same with me lol
add drain o , it will help
