Bill,

Without actually seeing it, this sure sounds like the carburetor to manifold
gasket.  It's supposed to be thick to reduce the amount of heat finding its
way up to the carburetor float bowl from the intake manifold.  If your
carburetor gets to hot (when using a thin gasket) the fuel will percolate
(boil) in the float bowl and cause havoc with idling and drivability... no to
mention the fuel will very quickly evaporate out of the bowl every time you
shut off the engine.  This makes restarts a pain... lots of cranking to refill
the float bowl before she'll start.

What's strange is that you mention it has no mounting holes!  This not right
and it sounds to me like you received a defective rebuild kit???  There should
be the four bolt holes in the corners of this gasket.  Typically in high
quality rebuild kits theses four holes will have metal sleeves in them so you
can't over tighten the bolts, crush the gasket and possibly crack the base of
the carburetor.  I'd give serious thought to taking the kit back for an
exchange... or have them replace just that gasket.

Yes... you most definitely need that piece, or the accelerator pump will not
function.  See if the auto parts store or Holley can sell you a replacement,
or maybe someone on the Digest has a defunct 2210C carburetor they could steal
the part from?  I have a Holley 2210C from my Traveler that I've moth balled
in perfect condition, so I'd rather not start parting it out.  But if you
really get stuck, let me know and maybe we can work something out.

Can you go back and carefully look around for the discharge needle where you
dumped the gas out?  It would be a shame to spend all that money on a rebuilt
just to get a little pump discharge needle!  If you do get a replacement carb
and it's the correct model, it should be a direct fit with no guesswork.

Good luck,

John
