You float is stuck in the up position. Inside the bowl in the carb.
A clogged radiator petcock can be cleared by first removing it entirely from the vehicle. It can then be flushed out with water or compressed air until flow is returned.
A petcock is a fuel swich on the petrol tank that can turn the flow of petrol to the engine on and off. It usually has a on, off and sometimes reserve setting.
Probably a bad fuel petcock on the bottom of the tank. It is vacuum operated so it will not flow fuel unless the engine is running. (Safety feature) My older '79 GS has a "prime" setting on the petcock that allows the fuel to bypass the vacuum shutoff and run straight into the carbs (thus filling the floatbowls should the engine not be able to start due to lack of fuel in the carbs.) Either you have a bad petcock or you are checking it in the "ON" position. If you have "prime" it should flow fuel without a problem. If not there may be dirt in the petcock or other internal problems. Hope this helps. Mark in NE Indiana. _____ I just fixed my 1983 GS750E which had a fuel flow issue with the petcock. After disassembly of the petcock it was found that the fuel valve o-ring would tack itself to the sealing surface, thus, not allowing fuel to flow. See this forum posting for a how to fix: http://www.thegsresources.com/_forum/showthread.php?t=141244
A petcock is a small valve used to control the flow of liquid or gas. Although petcocks are used in a wide variety of applications, the following passage will describe one of the most common applications of the petcock which is the control of gasoline on a motorcycle engine
Off. If this is left on, it can allow fuel to enter the cylinders which can wash down the cylinder walls and even contaminate the oil. Some newer motorcycles include a vacuum or other control in addition to the petcock that will shut off the fuel flow once the engine is not running. On these models, leaving the petcock On no longer matters if things are functioning properly.
The gas cock, also called a petcock, is a small valve at the bottom of a motorcycle's gas tank that allows to shut off the flow of fuel to the engine.
There isn't one, it works off of vacuum from engine when running, when you turn off ignition the fuel flow stops.
turn 1/4 counter clockwise= fromright to left. use pliers, very difficult to grasp-no room. petcock will turn and pop out enough to let water flow. twist-n-pull seems to be all the rage in detroit. simple, but effective....read--CHEAP
I think you may find that the letters ar Pri - Prime - the position of the petcock that will allow fuel to flow freely all the time. Should only be used when the carbs are empty of fuel (eg when carbs have been drained or bike not run for some time. Leaving the petcock in this position may lead to hydraulic lock in the cylinders if your carb float valves do not seal perfectly. So only use it in this position to refill carbs if they were thought to be empty.

The 1995 four runner radiator drain plug is at the passenger side of the radiator at the bottom. It is a petcock, so you only need to loosen it until the coolant starts to flow.
check your floats and make sure there is no rust in the tank and you have sufficient flow through your jets.
