urq fuel cap spitting gas, HELP!

[John Karasaki <johkar@teleport.com>]

Alright, I've had it with this problem.  I thought I had it solved by just
not filling up the gas tank.  Now gas is leaking past the gas cap even when
I only fit the tank 1/2 full.

Here's some background.  1982 urq with a gas tank from a european urq.  e.g.
it does not have the unleaded fuel restrictor flap.  If you remove the gas
cap, you look right into the filler tube.  There is a single bar nozzle stop
and a flat piece of metal welded to the bottom part of the filler tube.

Is this tank vented?  Maybe one of my vent lines is kinked or plugged.  Any
ideas?  TIA.
