RE: [Chrysler300] 300C carb id needed

Your 300C WCFB?s can be identified as follows.

1)       The air horn (top) will have casting no. 1310 near the corner screw
and I think has a 1 in front of that. Grey matter is dieing and cannot
remember all the no?s.
2)       The bowl casting (center) has 53 in a small circle at one corner of
bowl. That also has a no. in front of that, out side the circle.
3)       If you have a correct pair, the primary carb (front) will not have
a choke. The air horn will not have been drilled for choke shaft or holes
not drilled and taped to mount choke. If those holes are present, then not
correct carb.
      4)  It is not uncommon that some remove the vacuum secondary looking
for a quicker response when they put the pedal to the metal.
I rebuilt a set for a Mopar guy and the vacuum butterflies and shafts where
removed. They put a large sheet metal screws to block shaft holes.
You can re-install if you have the parts. If you do not have the parts you
are likely out of luck. To my knowledge they only came on dual WCFB carbs.

If you want me to confirm the casting no?s let me know. I can photo them.

Two of my 300Cs don't have electric pumps to make starting easier after
standing, and my little bottle of fuel to tip some in rear carb made me
notice something wrong/odd when I went to move it so I could mow the grass
that had grown up under it over what was a pretty dry winter luckily.

And so after another hot mongrel 110 degree day here yesterday, I thought I
would tackle something simple - namely find out why fuel seeped out around
where the rear carb bolted onto the manifold - this a sign to me there might
be a gasket problem.

First question - on 300Cs, what is correct gasket under carbs - the rear one
had a sort of asbestos/grey type material with a steel shim centre - this I
presume to block heat.

Second question - this 300C has carbs that have no rear counterweighted top
throttle plates - I know this not usual - wrong? The carbs are correct
looking WCFBs otherwise, but when I took rear carb off to remove remains of
old gasket, I noted no numbers stamped at front, but instead 1446 stamped on
underside where it would normally be hidden by gasket - anyone know what
this number means ? Or is it a SR number perhaps?

This 300C has always run like a pig, seems gutless re other two, despite
seeming good motorwise - I have never checked valve clearances, and they are
not as rattly as other two - maybe I will check this next. The car had real
early transitor ignition, bit of other go fast stuff - so maybe some early
hot up mods - carbs might be origs with baffles removed, however looks
factory type plugs where counterweight shafts would come tjhrough carb
bodies. Does this stamped number say anything re what carb is off/for?

Third question - can you buy the fine springs that are on the (I think)
metering rods that move up and down inside the carbs? Maybe they are wrong -
as motor is a bit better, more OK, once not on idle.

Fourth question - I have a Carter (AFB I think ?!) off a 57 Imperial 392 -
today I realised they are same bolt/gasket pattern as 300C WCFBs - and would
fit if one angled the brake vacuum pickup where screwed into intake
manifold- is this true, and has anyone tried a pair of them on 300C, rather
than the somewhat flawed WCFBs, and did 300D or E use this type?

Good news is car runs a bit better, and unlike last time when I only moved
it 25 feet forward, this time I didn't run over an old fence joiner that
likely had been lying unseen on ground for maybe 20+ years - couldn't
believe next morning tire was flat and saw it sticking on tire tread - I had
only moved it a few feet!!! (Reminds me of my vintage car days and hot
weather - I would be up paddock or if in the house, and when over 110
degrees one would hear like a loud explosion, rush outside, and amongst near
30 old cars around sheds/house, one quickly looks for the dust, and the
flat/blown tire engulfed in dust cloud - old T Model Fords had beaded edge
tires and with age and heat the bead would let go - that and old 21 to 24
inch tires that needed high pressures. Modern large 14 inch tires might be
harder to get lately in narrow whitewalls, but give me them any day over
changing old vintage and veteran rims/wheels.)

this weekend now suffering record rain/floods on east coast - 17 inches rain
in just over a day where that amount nearly is a good year's average
