Not sure what you mean by flowing through the valve (which valve? Tank is off the bike))... I'm not getting a flow anywhere! I know there is gas in the carb inlet tube, and I removed that inline filter that is in the 'T' connector. But I cannot get any gas out of the carb drain plug - so it's stopped somewhere between the two and nothing I've done so far has been able to unblock it. Only thing I can think of between them is a needle valve stuck closed... and it is refusing to open up for some reason.

Actually, the gas was not all that bad - it was just starting to turn... so the fact that it blocked up so hard in such a short period of time really has me stumped.

There is only 1 fuel valve (on the tank), presuming your fuel system has not been modified.
