Start the engine and urn the fuel off...
let run until the fuel is consumed that remains in the carb.
this will lower the float to its lowest possition and allow any crusties to dislodge from the float valve so it can reseat itself.
if the leak is from hardened gaskets , then you will need to address that with a carb kit.
good luck !
happy motorcycling!

SOURCE: Fuel leaking from bowls on Carb

is the leak coming from the overflow or just the seal around the bowls? if you take the bowls off (turn petrol off first) the floats may be getting caught open?

SOURCE: need setting for carb. adjuster on bottom of carb

Turn the adjusting screw all the way in until it LIGHTLY seats. Now back it out one and one half turns. Do the same adjustment for the throttle screw on the right side of the carb. You are now back to the stock factory settings.

Could you take a moment and rate my answer? Thanks!

SOURCE: carburators leaking

Tap the bowls with a screw driver handle while the gas is turned on. Your floats are sticking. If that doesnt work then you have to take the bowl off and make sure your floats are not bent.

SOURCE: Gas vent line on the bottom of carb bowl is

like said above, floats were stuck, give the carb a good cleanin, make sure the float rises up and down but stops were its level and doesnt go any higher or the bike could run like ****, take out all the jets and make sure you can see right through the top of the carb, also make sure not to over tighten them when putting them back in and if there is any dirt or anything in there stick a peice of copper wire or something along those lines and clean in out, clean and good operating carb is key lol

I have gas leaking out of the bottom of the carbs where the drain plugs are. It only leaks when the bike is moving. Does not leak idling. It idles perfect and runs out perfect no spitting and sputtering or...


Possability the inlet seals on the float bowl are hard or just old and when you ride- the vibration allows too much gas to flow past the inlet seals causing the float bowls to overflow.

How long ago since the Carbs were serviced?.

Leaking gas from bottom of carbarators How do I turn valve off


on the bottom of the gas tank there should be a petcock -- turn this to OFF,, this will stop the flow of gas to the carbs. now to fix this problem -- the most likely cause is a stuck float in the carbs. remove the carbs from the bike and remove the bowls,,, spray carb cleaner on all parts and amke sure the bowl and seat move freely. re-install and all should be good.

Leaks gas


the needle and seat in the carb isn't seating. First, shut off the petcock, and drain the fuel bowls with the screw on the bottom of the bowls. Let all the gas drain out of the bowls.Tap lightly on the carb with a small hammer, the refill the carbs, see if it still leaks. if it does, you need to pull the bowls off, remove the float and clean out the needle and seat, and put it back together

Carb leaking


You have a carb float stuck open. Turn off the gas and drain the carb. 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 and clean it with a spray carb cleaner. Be sure main jet is clear. Clean the air filter then re-mount carb.

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 water trap bowl ). Install an inline fuel filter. Turn the gas on, wait a moment for the float bowl to fill with gas then give it a try.

How long since the carb was serviced? Has the bike ran properly since the service?

Please rate this solution. Thanks!

My wife has a 750 honda shadow spirit 2003 dc that is leaking gas at the boot that fits from the bottom of the carb. to the front cylindar what is causing it and how do i fix it


This sounds to me like a carb float being stuck open. 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 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 water trap bowl ). Install an inline fuel filter.

THis should solve the problem.
