Greetings all,

I have a '75 spit, manufacture date of Jan1975 (according to the plate),
engine number 30xxxU.

I seem to have very little (if any) vacuum at the distributor.
I know about the missing gulp (anti-runon) valve, it is missing, but the
lines are plugged.  Take out the plugs and the engine stops.  I assume
that plumbing is correct.

The carb (CD150) is in multiple pieces awaiting kit from BPNW ($17.50),
and it looked fairly? good except for a tear in the anti-deceleration?
valving.

Coming from the carb are two pipes that feed a lozenge shaped doohickey,
that subsequently feeds the distributor and (can't remember now)
something else.

What *are* those doohickeys?  Are they needed?  I figure to take them
out unless some purpose in life can be proven and plumb straight to the
needed locations with 1/4 ID tubing for vacuum.

Am I stupid?  Any thoughts, recommendations, etc regarding my loss of
vacuum would be appreciated.  When I drove it down here from the buy, it
had *NO* vaccum at the distributor, and I figure that needs to be
rectified.
