Default 82 Accord carburetor problem...floods out...won't start

1982 Honda Accord sedan, auto trans. It has a problem with the
carburetor. The car barely starts, if at all. And if it is started,
it won't rev up. And then it stalls out and it won't re-start. It
fills like it is totally flooded.

The 2 float levels look good through the small windows. I pulled the
top of the carburetor off and it looks good inside. The 2 electronic
accuators work fine.

This carburetor has 3 barrells. One is just a very small auxillary
primary and there is also the primary and the main.

I don't know what is causing the problem. The engine compression is
good. The engine timing and ignition timing are fine. The weather
and/or temperature is not a factor.

The problem was previously diagnosed as being in the carburetor system
by a reputable garage. But, what part is bad. I don't want to replace
the carburator.

Could it be something in the emmision control system ? Does anybody
know what the problem is ?

If you are sure it is the carbuator, I advise you to visit some auto parts
stores and see if they can sell you what is known as a carbuator kit.
Carbuator kits come with everything you need to rebuild the carbuator.
Hopefully, it will come with the instuctions you keed to rebuild the
carbuator. If not, those instuctions can be found in some repair manuals
that can be purchased at auto parts stores and Barnes and Noble. Don't buy
the manual until you make sure it has detailed instuctions and pictures
related to rebuilding a carbuator. There are dozens of gaskets and other
parts in a carbuator that can "go bad" or no longer work the way they were
designed to work. One leaking gasket could be the source of your problem.
Also ask the auto parts manager if they have rebuilt carbuators for
sale--it might be easier for you since you won't have to go to the trouble
of rebuiding your carbuator which is a lot of work.

The "some auto parts store" you should visit is the Honda dealer. They sell
what is known as a top clean kit. This contains all of the parts that will
be needed to overhaul the carburetor except for floats which must be
purchased separately. It also includes detailed instructions. The top
clean kit and protocol was developed many years ago by a dealer tech who was
looking for a faster way to overhaul Honda's carbs. The carb is left bolted
to the intake manifold and just the top air horn is removed (and the mixture
screw along with the side solenoids as well).

With a flooding carb, you can often see the extra gas dripping in the
barrels. Have you checked this?

Another thing to do is to do a propane enrichment test. Since the float
levels are ok, the symptoms you describe could be indicative of a carb
that's too lean.

This was standard for Honda carbs except for the side draft models used on
the Preludes. I strongly recommend that you NOT adjust anything to do with
the auxiliary barrel. These are set at the factory with a special gauge and
usually don't require any adjustment.

I would suggest that you find an independent Honda shop in your area that
you can trust to do the diagnosis/repair. Another option is to purchase a
factory service manual from http://www.helminc.com.

By the way, a peculiar problem that sometimes happens to Honda's carbs is
that the brass jets in the bottom of the float bowls can fall out of the
body of the carb. This can cause flooding even if the float levels are ok.
However, this condition is easy to spot especially since you've had the air
horn off since the jet will be rolling around in the bottom of the float
bowl. I've repaired a couple of these by lightly scoring the side of the
jet so it has increased interference with the bore in the body of the carb
and then gently tapping the jet back in place.

These Accords had an issue with floats that sank, flooding out the
carburetor and ended up getting gasoline into the motor oil. I would suggest
you call your local Honda dealer and obtain a float kit, should still be
available and change the oil and filter as well. Should take care of the
problem
