[Fot] Weber carb issue

[McKearn McKearn]

Hi All.
  I have triple webers on my GT6 and one carb does not respond at all to
changing the idle adjusting screws. This is the number three carb. which is
at the rear of the engine. It is also leaking a bit of fuel when fuel pump
is on with engine not running. Fuel pressure is 2-3 psi.  This is the first
carb in line after the fuel pump. Could this be a float problem?
  Thanks P.J.
