Using things in a pinch.

engine.Bottom vacuum hose (I think it is about 3/8'' inside diameter
hose) is cracked and almost busted in two pieces where it connects to
the bottom rear of the carburetor.Now the engine runs way too fast.I
can't drive my van untill I find something to use in a pinch so I can go
to an auto parts store for a vacuum hose.

Ad absurdum per aspera
around with enough duct tape, coathangers, removed but still decent-
looking hose clamps, high-temp plumber's epoxy stick, etc. to give
McGyver a late Christmas. See also Gorilla Tape (a superior product
that has led me to cheat on duct tape for heavy-duty applications),
self-fusing electrical splicing tape, etc. This would be a temporary
measure, mostly because none of these things are really quite up to
underhood temperatures in the long run, but should get you to the auto
parts store.
If you don't have suitable tape, chew some gum. While masticating,
contemplate your engine and see what other vacuum hoses you need to
replace, one by one, as long as you're at the auto supply. (This one
got your attention because of a big vacuum leak in a bad place, but
you may bet that some of its buddies down there are in not much better
condition.) That should get the gum good and ready for its second
act, used in a pinch figuratively and literally as a sealant.
If it is not a custom-shaped hose, you might consider flipping it end
for end in an attempt to get the ruined part (probably the one nearest
the greatest heat dies first) into a better position for improvised
repair. For that matter, think about whether it's long enough for you
to cut off the bad part (definitely a "measure twice, cut once -- or
less" situation though), again as a temporary measure. Make sure it
wouldn't be interfering with any moving parts or resting on something
hot before doing either of these things.
Best of luck,

Autozone store, the store didn't have the carburetor vacuum line hose I
wanted, I bought some fuel line hose and I put that on my Carter Thermo
Quad 9342S 256 2 carburetor in my 1983 Dodge van.That didn't solve the
problem as far as the engine running too fast and not running at idle
speed is concerned.I have never worked on or rebuilt a four barrel
carburtor before, I think it is a four barrel carburetor anyway.
On my way back home from Autozone, I checked at O'Reilly's and NAPA,
they didn't have a rebuild kit in stock and neither did Autozone, they
didn't have a rebuilt carburetor in stock either.A rebuilt carburetor
cost anywhere from around $340.00 up to about $370.00 or thereabouts,
depending on which local area auto parts stores around here sells them.I
don't want to drive my van anywhere now, because the engine is running
too fast now.Anybody have any ideas what I should try next to get the
carburetor working ok?

If it's not the vacuum line, possibly a stuck choke? Is the small
butterfly open or closed on top of the carb? Closed usually means
choke which can cause the engine to idle fast.
cuh...@webtv.net
it.I don't think the carburetor has ever been serviced or worked on
before.Yesterday, I noticed the choke rod is broken at about the middle
part of the choke rod, I know for certain I didn't break the choke
rod.The butterfly plate in the front part of the carburetor seems to be
stuck in the open position.I sprayed some carburetor cleaner down into
the carburetor and all around the linkages.I wiggled all of the linkages
with my fingers.I didn't see anything unusual, except for the broken
choke rod and the bad carburetor vacuum line hose which I have already
replaced with a piece of new fuel line hose.
Yesterday, I was reading about Carter Thermo Quad carburetors on the
web, some models of those carburetors have tamper proof choke units on
them.I believe I can get that tamper proof choke unit off if I want
to.Maybe somehow I can braze weld the broken choke rod back together
with a handheld propane torch and some old brazing rods I have here.

Sure, but remove the part. I wouldn't braze next to a
carburetor in situ!
Also, disconnect any bimetallic coil from the linkage rod.
On some model Carters (I don't know your model) the fast
idle cam plate can flip upside down when parts are worn and
the choke is disconnected leaving a random (fast? slow?
whatever) setting.

alternately, if you have a good junkyard nearby, just ask if they have a
thermoquad in their "recycle" pile. I've gotten little linkage bits and
pieces that way, by paying a buck or two for a carburetor that the 'yard
had determined was scrap anyway. I had the exact same problem on a '67
Dart - a PO had disabled the choke by mangling the actuating rod.
Probably worked OK in North Carolina, not so much in PA in the winter.
A few minutes of rooting through a 55 gallon drum of junk carbs and $3
later I had a parts carb of the same model from which to scavenge
linkage bits.

check that.Sure, I know to remove the broken choke rod and the
thermostat before I try brazing the rod back together.Actually, I want
to rig up an old style manual choke control similar to like the old cars
and trucks used to have, but I don't know if that would work ok on that
particular carburetor.

This one did that:

I have changed several similar ones to manual choke over the
years. Not difficult at all.

They stock a bunch of parts and kits for older Dodges.

squeez the lever, the jaws are suppose to spread things apart.It seems
to be working, but it is very, very slow.The middle section of my Thermo
Quad carburetor is made of phenolic plastic/whatever, and I don't want
to break anything.Is there some sort of a ''Trick'' for removing the
three main body sections of Thermo Quads? I already have removed all
eight of the screws that were holding the three sections together.Unless
I missed one or two screws that I didn't see.

You might have missed something.

Here's a link to the blow-up of this carb. There's 10 screws holding the
body together. Please note in the instructions about 2 screws (35)
located by the choke and air horn. Too bad the diagram doesn't really
give a good idea of where these screws are located. Good luck!

it down.I am glad I saved back a piece of one of the top/bottom
horizontal wires.The diameter of that stift piece of wire is almost
exactly the same diameter of the broken choke rod on my Carter Thermo
Quad carburetor.I just now finished up with making a new choke rod from
that old piece of fence wire.
Using things in a pinch can be a Martha Stewart Good thing.
