Tell me if I'm wrong but just in case so I don't do the wrong thing this is happening because I need to change my float height right. I'm more or less thinking on terms of a toilet bowl. When the toilet bowl float gets high enough it stops the flow of water so it won't overflow in this case the float I stops so the gas won't overflow but those hoses are there just in case it does because the Engine requires sprayed air rated fuel not liquid fuel correct?
It's more than likely a float stuck open because of debris in your needle and seat, Sometimes a tap on the side of the bowl with something solid will dislodge it, if not you'll have to pull the carbs apart to check. There's an o ring under your needle and seat that could be damaged letting fuel past even if the float is closing.
Seeing you've got the airbox off already, I'd pull the carbs off and give them a good clean, checking everything as you go.

:hi: I had a similar problem with my 'new to me' '92.
The 'fix'...contact these guys www.siriusconinc.com (http://www.siriusconinc.com) and buy 4 x complete carb kits for your puppy...way better than Depends :mocking:
In a couple of hours you can: strip, clean, rebuild with new carb kits, reinstall, dial in and VOILA :yahoo:
Job well done for another 20+ years!!!
John.
yup, the first "project" for your project bike should be rebuilding the carbs- and thats for ANY 30year old bike
newly rebuilt carbs will make you happy for more reasons than stopping leaks
Tiger's suggestion was good but, if you want easy and accurate just send them to Randy at "RPM"
if you search the forum for that subject you will see that it is damn near "plug and play" when you get your carbs back- very little adjustment(if any) needed
and the owners are ecstatic about the way the bike performs after the service
chemical dips available at the auto parts stores cannot clean anything like the ultrasonic methods the pros use, not to mention the experience of the person doing the work, how many thousands of FJ carbs has RPM cleaned and tuned?
-i think this costs around $200, a small price to pay for the above

Weaponworth,
Closed spaces and gasoline fumes are the recipe for a serious disaster, which may include the entire garage, or even the house. Park the bike outside, under a cover, until you get this problem under complete control.
It's likely that for one or more carbs, you have a little debris at the needle-and-seat, or a bad a bad seal there. Plug each overflow line with a twist of kleenex, and you will find out which one(s) may be leaking. A bad needle-and-seat can be replaced, without rebuilding all the carbs. In any event, the fuel pump (when the key is OFF) should shut off the fuel flow from the tank, and
that is not happening. either. Working outdoors, unplug the fuel line from the fuel pump outlet, and run a hose from the fuel pump outlet to a catch container (gas can). Turn on the key and let the fuel pump run freely for a few seconds, then turn off the key and see if the fuel pump stops the flow, or just keeps leaking. Repeat as necessary. If the fuel pump is faulty (always leaking when the key is OFF), you will need a new fuel pump. RPM (Randy) has aftermarket fuel pumps that cost much less than OEM.
Cheers,

Okay cool thanks guys I'll definitely take a look at those options. I'm a so phone technician and we have a big ultrasonic bath tool that we use if I put my carbs in there one by one and clean them that way that should be fine right.
Maybe a day or two late but here is my best advise. Ultra sonic cleaner at your work should work great, just make sure the cleaner won't damage the carbs. Order this. http://www.rpmracingca.com/proddetail.asp?prod=carbkit&cat=24 (http://www.rpmracingca.com/proddetail.asp?prod=carbkit&cat=24)
On the main page number 7 down from the top is the files section, tons of good information. This will walk you through a carb rebuild. Then all you need to do is synchronize them.
Hope this helps. Kurt
