carb

[cablewarf]

I'm looking to rebuild my carburetor. Get my hands wet for the first time. But i'm not really sure what kind it is, or what i'll need to do this. I do know it's a single barrel. any tips? thanks in advance.

Get some part numbers, what type of engine is it on.

post a pic of it. check the numbers from the little tag on the front of it hanging off of the front top bolt. you will need to soak the cabr in cabr cleaning solution and a rebuild kit. follow the instructions in the rebuild kit.

Here is a picture of the carb. Wheres a good place to buy a rebuild kit? it's on a 1978 a-1 4.9 300

That's a Carter YFA 1-bbl carb, which was used by Ford from (I believe) '75 to '86. (It was also used by Dodge, Jeep and AMC). Look on the driver's side, at the carb base. What you need to find is the 4-digit number that starts with a 7 (like '7262' or '7305'), or a variation of the Ford numbering system, which will look something like 'D8TE-CAN' or 'D8TE-AAA'. Once you have those numbers, you can go to any decent auto parts store and get a rebuild kit. While you can probably just tell the guy at the counter that you need a kit for a Carter YFA from a '78 300 and be OK, I'm not sure how universal those kits are.

Here's a link to read about the YF and YFA carbs:

I just rebuilt my 2 barrel and it was not that bad. Like Fordman said, just follow the instructions and remember how everything went together.

The Carter Y-series is a really simple carburator and an excellent platform to do your first carb rebuild.

As a side note...........be sure to mark all vacum....and fuel lines..........and electrical or mechanical connections............nothing will mess with a good rebuild like a faulty reinstallation.

The Carter YF is about as easy a first carb to rebuild as you can find.
The only parts in it that actually go bad are the needle/seat and the
pump diaphragm.. Get everything real clean, and change those out,
along with the new gaskets and you should be good to go.
Be sure to check the float for any leaks if brass. Also make sure
to check the float drop, etc..
The instructions are in the kit. And yes, most YF rebuild kits will
cover most all YF carbs. They made a feedback version, but none
of these old trucks use them normally.
Like I say, the only parts that really wear out are the float needle
and the diaphragm. There is not much else to go wrong unless the
throttle shaft bores get wore out, and it leaks too much air in.
BTW, get everything as clean as possible, including all idle air
ports, etc.. Just a tiny spec of dirt in the wrong place can cause
you to pull it off again after rebuilding.
Both my trucks have the Carter YF. I can rebuild one in less than
an hour, including taking it off, and putting it back on.
They are easy.
The number one problem is usually a leaking diaphragm.
If you yank the carb, and it's leaking from the base, or looks
like it has, and also runs rich no matter the idle setting, the
diaphram is probably shot and leaking.
The modern gas eats those things for lunch. This includes the
new ones that come with the kits..
You have to unhook the pump linkage and pull the pump shaft
up to get to it. Remember the order of the springs and keepers..

BTW, one other note.. When you pull the top off, there is a
little check valve up on the top in a little hole/port..
Some are a check ball and spring deal, and some use a little
brass check valve that looks kind of like a hex shaped pin
with a point on the end.
If you invert the carb, this check valve will fall out on the
floor.
So first thang when you pull the cover off, catch the check
valve and store it away before it gets lost.
I recommend reusing the same one that was in the carb.
But if it gets lost, they do include a check valve or ball
with the rebuild kit.
I've forgot about that check valve and inverted the carb
and had it fall out.. Scouring the ground looking for tiny
check balls etc is no fun.
