82 gs750ez carb problems (please help)

[Anonymous]

i have an 1982 gs750ez i cant get the gas to quit leaking if i do not hook up the hoses to the air filter the gas will come out at the carbs face but if i hook them up it comes from the breather hose at the top of the engine the hose begins to leak gas and starts to steam

Can't quite figure out what you're describing here. That said, you should have a vacuum line from the front of carb #2 going to the smaller fitting on the petcock. A larger fuel line going from the large fitting on the petcock to the carbs to supply fuel. The crankcase breather tube going from the valve cover to the airbox. Two smaller vent hoses from the bottom of the tank to the rear of the engine and just left dangling. If that is all correct you either have a faulty float valve, leaky petcock, and maybe both.

Did you take the float valve seats out of the carb bodies? They have o-rings on them that the fuel can get by. They dry out and shrink up with age. Especially if a spray type cab cleaner is used.

The float valve seats are the parts that the float needles slip into and stop fuel flow when the floats push on the needles. You have to remove the floats and a small screw to get the valve seats out of the carb bodies. Be very careful removing the pins that hold the floats in the carbs. You can easily break the towers that the floats pivot on.

Just pull them straight out. The o-rings are on the valve seats. Use a little oil on the o-rings when reinstalling them. It's easy to shave a bit of the o-ring off putting the seats back in. The o-rings that come with repair kits for pump up type garden sprayers fit perfect if you have trouble locating the right size. There is a guy that frequents this site by the name of Robert Barr that sells o-ring kits.
