The Valk has been sitting for over a month in the garage. The battery was dead so I jumped it from my wife's car (not started) with the choke on. It started up after a few tries, but almost immediately started POURING gas out of the carbs. I looked like there was gas leaking out of the three on the right for sure, and my wife said there was gas coming out of the carbs on the left as well.
Any thoughts? Dry O rings? I am supposed to be heading to Inzane and don't want any issues before heading out of state.
Thanks
Update: Went out after dinner to start sorting out where the leaks were coming from and when I started the bike up, not a drop of gas leaking from anywhere! Not that i am complaining, but now I will need to keep an eye on things at least for a while. I have a feeling that it was the stuck floats that were mentioned in this thread by Deez, and they "reseated" themselves once the bike was fired up again. It had been sitting too long in the garage in the 100+ degree weather and I think the floats stuck when the gas in the bowls evaporated.

I would assume by what you state that you did not look yourself, at exactly where all the leaking was occurring.
It would have to be extremely rare for all six carburetors to be leaking gasoline.
I suggest you apply a vacuum to the gas stopcock and investigate yourself as to exactly where the gas is leaking from.
It may take some time and a lot of investigation to arrive at a proper conclusion, but to try for a fix, for your problem with such little information would be an exercise in futility and have no credibility.
I suggest to not try to start it with this condition you're reporting.

I recently experienced the same thing while out in Colorado. The original cause may be different but the experience is the same.
the floats are not shuttting off the fuel , the bowls then overflow out the vent tubes (which a joined to a common drain , pouring all over the engine. in my case , i just came down out of the mountains into Denver on a day that my Motion ambient temp gauge was reading 115 deg. (a record for Denver) the build up of pressure in the fuel line (i have a belly tank with electric pump) was more then the needle and seats and floats could handle . fortunately after stopping for an hour everything had cooled to the point of letting me tap on the bowls with a wrench to jar the floats enought to unhang the needles and they reset . In your case I believe the bowls went dry and the floats stuck down in the lower position, allowing the bowls to overfill. try gently tapping on the bowls , pull the sparkplugs and bump the engine over to clean out the cylinders (dont want a hydro lock) the try again.

Not trying to hijack the thread but I have question that is revelant to this problem. The parts fische shows two 'spider' arangements of tubes connected to the carbs. One is connected to the carb drains. I suppose the other is connected to the carb bowl vents. Is the one connected to the vents only on California bikes and Valks for the other 49 states have the vents unconnected?
If the all of the Valks have the 'spider' arrangement of tubes connected to the carb bowl vents, then how does gas get dumped on the engine when the float valve sticks open? I would think the gas would be dumped on the ground in front of the back wheel.
The reason I ask this is that my bike had the same problem (gas being dumped on the engine when it was running) when I bought it.

I believe they are vent lines that go to Ca. canister. When i desmogged I put a fuel filter in place of the Ca. canister. Isn't there just a plug where the carb. vent nipple goes on non Ca. bikes.

I could be wrong but I dont think the 48 state carbs have the individual vents on each carb.
My original set of carbs didnt have the vents my take off set does....which because of my bike being desmoged I just plugged all 6 vents with silicon caps.
Same with what appears to be a vent on the fuel rails.......
None of these vents were on the original set of carbs.

It takes more than a month or two to allow the gas to evaporate from the carburetor bowls.
Jus sayin'
