    Thank oyu Alcatrazx for your quick response, and yeah you are right, Ihave to be more specific, we shut off the gas valve after every ride and suddenly when I was getting the bike ready for a ride, open the gas valve and gas was comming out of the mentioned hose without stopping, and every time I open the gas, there goes the same problem, even without touching the throtle, just by opening the valve, this happened about a month ago and I haven't been able to ride it due to this, it sounds weird, but I'm pretty sure being a pro, you know what's going on.

    thank you again

I had this same problem on my DRZ-110.
I took apart the carburator to clean everything out, but when i re-assembled it it started to leak gas out of the drain hose. Then i found out that the problem was that one of my gaskets were torn and were letting air in the drain which prevents it from being a vacuum, therefore causing gas to leak out.
I would first check the float & make sure it isnt stuck, then i would check all of the gaskets and make sure they arent torn, & replace the ones that are, even if theyre slightly damaged they can still let in air.
Your carb has to be 100% sealed & vacuumed to prevent any leaks & for it to work fine, so get those gaskets checked out

If your float, that's in the bowl of the carburator is sticking, it won't "float" as the fuel fills the bowl and never stop the fuel from entering, causing it to run out the overflow vent hose. The float is what regulates the amount of fuel that goes into the carburator bowl. You can try to tap it with a screw driver handle to see if it might stop while it's doing it.

Your carb works a bit like the rank behind a toilet. The fluid (gas or water) comes in, float goes up, which pushes a valve shut, fluid stops.

If this "just happened" you very possibly have a bit of dirt blocking the valve (easy fix). You could also have a stuck float or even a flooded float.
One word of advice: try not to disassemble the carb over gravel or dirt - there are small parts that can fall out. Also, unless you understand how carb mixtures work do not mess with the adjustment screws other than the idle adjust.

Hi

If i got you right, this will always happen if the pipe is lower than the carb its a syphon effect so it will always happen. You either have to place your question more specifically because as such there is nothing wrong with that.

Hope that I was of help :)

    Hi There



    From what i get, this is a kids' bike. If the gas keeps coming out it means that there must be a crack somewhere. The reason being that there must be some air coming through because the fuel keeps coming and its not stopping. You will be required to check from the tank cap all the way down to the hose joints to the valve itself as there should be a crack somewhere preceeding the valve. If the valve itself needs to be replaced i reckon it might cost about $45 to replace and might be more handy to replace it with some improved ones from the 08 model. Hope that this was of help to you :) for plastic parts if they are cracked such as tank cracks etx you can use epoxy-like glue where as for metal clips and pipes they can easily be replaced with new ones. Hope you get biking about soon :)



    Best Regards

One end of little black hose came off my sons yamaha pw 80 yzinger so when u turn gas on it comes out end. not sure where it goes.


Just guessing because I can't see what hose your talking about but if gas is coming out the hose when you turn it on I suggest looking at the carburator and I suspect the hose came off the inlet to the carburator. Thats the only place gas goes after leaving the tank, if it is coming out the overflow for the carb then your float is stuck. Some bikes have an overflow hose for this reason and it does not connect to anything just hangs down to let gas drain from the carb.

Fuel leaking from hose on bottom of carburetor


This happens when the float in the bowl sticks open. On a carborator the bowl holds gas. When the fuel pump fills the bowl the float raises and is pushing a needle valve that shuts off the gas until the float goes down and the needle valve opens and adds more gas. sometimes is sticks or the needle valve doesnt seat properly. You should rebuild it, buy a carb rebuild kit for your type of carb. It comes with new needle valves, just remember how it came appart.
Good luck

My 2005 carburated sporty is leaking gas from the hose on the bottom of carb is my float stuck


That hose has dual functions; to drain the carb and to safelydivert gas if the float valve fails. Check to make sure the drain screw isn't open or loose. If not check the float and needle. The needle could be deformed as a result of ethenol exposure. Safe riding.

I have a 06 honda trx250ex put new gas and oil in it and plug and battery and iit turns over but wont start but when i put started fluid in where the plug goes it starts for like a second or so and quits...


your problem is a clogged carb. clean float valve, main jet and idle circuit with a can of spray carb cleaner.

disconnect fuel hose at carb and see if gas flows.

reconnect hose and open float bowl drain valve. If no gas tap on side of float bowl with plastic end of screwdirver to free up float.

still no gas? remove float bowl and try to shoot carb cleaner into the fitting for the gas line from tank.

if gas flows now then put it all back together and it should run

if not then remove carb and clean carb passages, main jet, idle circuit.

Hi. I've got gas leaking from two carb drain hoses with the gas set to OFF. Is it the carb, the gasflow valve or both?


Thought I answered this...Pull off the fuel hoses at the valve and check that flow stops in the off position. Remove the 10mm head sediment bowl and check for dirt/rust. Sounds like 2 float valves are leaking because of dirt or foreign matter. Pull off the float bowl drain hoses on the carbs and loosen or remove the drain screw to check the fuel condition.

Honda 750 shadow gas leak


It is a vent / overflow hose. It drains to the atmosphere / street. If gas is coming out and isn't stopping then a float is stuck.

Turn off the gas and drain the offending carb(s). Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb(s) and look for any misalignment of float pin, needle or adjusting tang.

Now re-clean with a spray carb cleaner. Clean the air filter then re-mount carb(s). Next, Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a trap bowl ). INSTALL AN IN-LINE FUEL FILTER..

Gas coming from black tube


Hi and welcome to FixYa,

Initially and to my knowledge, some of the hoses connected to a carb would be:
  • from tank through fuel shutoff valve;
  • overflow hose;
  • drain hose;
  • in some case a vacuum hose.
Of the above, the only possible hose that would fit your description would be the overflow hose. Should this be the case, then this indicates that the float inside the carb's bowl has not moved up to engage/close the inflow valve. A workaround is to tap the bottom of the bowl to jar the float to go up as well as the shutoff the inflow valve. The drain hose would also allow fuel to flow out from the carb but that would mean the drain screw is loose/opened.

Good luck and Thank you for using FixYa. Happy Holidays.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.
