HIF-4's problem

[Nelson Yaple <Nelson_Yaple@ccm.hf.intel.com>]

          I had a similar problem on my 72 MGB-GT the rear carb was
          pouring fuel out of the jet.  The problem was the needle was
          incorrectly installed.  It must be biased to the rear of the
          jet.  There is a nip in the seat of the needle that provides
          the bias, it has a mark embosed into it.  I can't remember
          it's orientation, I believe the Haynes manual shows it.  
          Good Luck.    Nelson.
