That o-ring is there; I know because I removed the needle several times and I
could feel it providing that nice snug resistance. I could also see it sitting
in there when I removed the #17 nut.

2) Verify that the o-ring, (#9) and packing (#10)on the volume nozzle
are in there. It can't suck fluid up the siphon tube if it can't pull
a vacuum with the venturi action.


Thanks Larry; I will check for those.


You do have a rubber-tipped air blow gun, right? They make cleaning
small orifices much, much easier. Doublecheck your flow from each of
the fluid nozzle orifi (orifizzes? while you're at it.

I learned to triplecheck everything when I was doing tune-ups and
rebuilding carburetors for a living. And to this day, I can still
honestly say "HOLLEY SUUUUUUUUUUUUUUUUUCKS!"
