Gas leaking from carb

When we turn the gas on at the gas tank, gas leaks out from the hose on the carb. If the motor is idleling the gas continues to slowly leak. If the motor is being ridden it does not leak. The more you are on the gas the less it leaks.
If you turn the gas off at the tank it stops leaking.
What do you think?

Why is bike flooding and pushing gas out top over flow hose on carb after it runs for a min or two. Carb float been replaced still doing it.


Hi, Paige and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaking float assembly.
7. Particle contamination in inlet fitting cavity.

Longjia 125cc raptor had problems with fuel leaking from the bottom of the carb and though the air filter. Just put a new carb on OK for a few day now doing the same any clues please


New carbs aren't known for leaking unless you had it open and altered some thing. A float can get stuck if you let it sit without using it. Should put stable in your tank and run it so thestable gets into the carbs.
Check above the carb for a gas leak from the gas hoses and check the gas tank. They may be running down onto the carb and just appears like the carbs leaking

2005 honda shadow arow overflows all the gas wile running its a 750


it can be very hard to correctly trace a gas leak.. Start with the petcock at the tank - make sure its not leaking, carefully move your way down towards the carbs..

If it is indeed the carbs - you will have to pull them and clean (possibly rebuild).. Either the floats are flooding / sinking and not blocking the incoming fuel, or dirt has stopped the needle from sealing properly, or you might have an external leak on the hoses / orings etc..

It might be your tank overflow - is the tank completely full when this happens?

Yamaha 1978 750 Special Fuel Leaking Problem


These type of fuel shut offs do not have a manual off position. They are automatically operated by engine vaccuum when working properly. They have malfunctioned and allowed fuel to overflow into the airfilter box(the black box) untill repair time use a long piece of hose to connect the large outlet of each shutoff to eachother or plug the end of two short pieces. The carbs have a drain screw on the very bottom of each facing left , right or straight down. you could also drain the carbs however once the fuel supply is cut to them they should not leak any further. Leave the carb fuel hoses from the tank disconnected. You should drain the tank by siphon and the residual gas that is already in the air box can be drained from the hose on the bottom of the box. This is a mess but once you get all this drained it should stop leaking

2002 Shadow: bike leaks gas from the carb, and runs with no gas going to it


Carbs have a reservoir in the base that will last for a few miles before it is drained. So turning the fuel off doesn't starve the engine immediately. This is normal.

When off gas is leaking


1. remove the hose from the carb and see if the petcock is shutting off the gas and if not clean, repair or replace the petcock.
2. look in the tank and see if it has rust in the tank even a small haze of rust as rust will cause the needle and seat to stick in the carb and make the gas leak. If the gas tank has a lot of rust it may need a tank rubber liner kit added or even a new tank to stop the leaking.
3. if the bike has been sitting for a while it may have trash in the fuel system(carb/petcock/tank). Rust or any trash can cause a leak. Properly clean out the carb and fuel system and add a new filter when done.
4. Improperly adjusted or bad needle/seat or float in the carb will cause continual leaking. Replace the needle/seat/float and adjust the new one when installed. Check your service manual for float adjustments.

I have a 1977 honda 750 as soon as i turn the gas to the on position gas leaks out of the overflow hose continuously. what should i look at to fix this.


You will need to drain the carbs then remove the float bowls in order to clean the interior of each carb. Use spray carb cleaner and pay special attention to the float pin. Right now some trash is stopping one or more of the float pins from closing fully. This means gas flows into the carb(s) and the carb(s) have no way to stop the gas. The trash could be a bit of old rubber gasket, rust from the tank, a sliver of grass, or "cotton" from dandelions or trees. Those are the usual suspects. Please rate my answer. Thanks.

My 1974 kawasaki ke 125 is leaking gas out the bottom of the engine. what is wrong with it?


Several things could be wrong. First, the fuel petcock (valve) at the bottom of the gas tank should be turned off when the bike is not being ridden. Also, it is possible the valve may not be fully shutting off the gas. This can allow the carb to overflow and leak gas. A stuck open or punctured float in the carb bowl can cause overflow. The float should be light as a feather and have nothing inside it but air. Is the carb securely mounted?

Check for cracked fuel hose or bad connections at the tank and carb. Is the fuel valve body leaking gas where it mounts to the tank? Heck, with the bike being 36 years old the tank may be leaking at a weld or due to rust through. I wish I could work on your bike. The older bikes are more fun to work on than the newer bikes. Post a reply and let me know what you find.

Gas leaking from hose that is under tank that is not for gas flow


is it an overflow from the carb? gas will only be in one of 2 tubes and they are the fuel line from the tank and the carb over flow. unless you have an electronic fuel pump then tubes go from tank to pump to carb. if its coming from the overflow then you are getting too much fuel into the carb float chamber. you may have a sticky float. thy getting some Berrymans B12 fuel additive and putting double the doseage in the tank. run engine til hot then leave it to stand overnight. this should break down any gum/varnish that has built up in the system

has this been in storage thru winter?

Fuel leaking out the overflow tube...


The overflow tube coming out behind the swingarm? If that is where it is coming from sounds like your float in one of the carbs could be stuck.
