Bad seal. Rebuild the Carb with a new kit and make sure you have no extra parts. You should be able to get a carb rebuild kit from your local auto parts store.

What is measurement of a float level on a carter one barel carburetor on a jeep cj5 1977?


1977 now that is a blast from the past.
finding books that old is hard, but are sold in book stores.
but from Carter, and very very old jeep books.
4 engine then
and 2 Carters, i see.
232/258cu-in, with YF carb
here ill paste the words

"To adjust the float drop, hold the air horn in the upright position and measure the distance between the top of the float, at the extreme outer end, and the air horn casting. The measurement should be 11/4 in. (31.75mm) to 1973, 13/8 in. (35mm) 1974-78. Adjust by bending the tab at the rear of the float lever."

I have a 1984 jeep cherokee pioneer 2.5 l.engine that has 360,000 miles on it. Almost immediately after I change the oil it reeks of gas. What are possible reasons behind this and how can it be fixed?


it's a carb engine and carb fuel pump.
redux for "IT"

OR DID "IT" MEAN THE OIL STINKS OF GAS.
NOT CLEAR.
i drained the oil and the catch pan stinks of raw fuel.
THE GAS DILUTED WITH GAS, CAN BE 2 THINGS.
ON CARB CARS.
1: THE BLOCK MOUNTED FUEL PUMP is bad and leaks fuel into the crankcase, badly and fast.'

2: carb float valve is stuck, open and fuel flowing like crazy out all jets and nozzles , un controlled...

84 XJ Pioneer. AMC 2.5L
not to many of these left on the road.
it had a Rochester or Carter CARB.
Ever check float levels on it?
or rebuild a carb? with new float valve, that does not stick?

take off air cleaner
stall engine, at same moment look down carb bore
(horn) does it still leak fuel engine off?
oops. (float stuck)
if not, then jump on fuel pump bad inside. replace it.

What would only let one side of carb get fuel and open up


its a carb, and as such only needs to have a constant float bowl level.
Te sami pump runs a regulator built in, you test that with a pressure gauge.
one side?
did you read the FSM on topic>
here
http://www.acksfaq.com/sitemap.htm
see chapter 4 on carb and pump
the carb has only one input, and that is fuel line to the float valve.
the pump , however does have a loop,
that is because it has a regulator and returns unused fuel to the tank,
kinda like EFI does.

The pump has 3 nipples, 1 suction port. and 2 pressure ports.
1 pressure port is the return line an the other is carb.
the return tube is the top tube of the pair.
the pressure reg holds pressure at 3 to 7 PSI
if the float bowl stays at spec level at all times, even full engine load.
then the pump ,float and valve all work as designed.
that leaves, carb internal problems/
never blame a carb , if the distributor adavance, parts are stuck.
check advance first. then tune carb.

1987 Dodge Omni 2.2 Engine Carborated. Starts great, runs 3 to 5 minutes and then starts to smoke, load up on gas and shut off. Wait an hour and same thing all over again. All tuned up. Any Ideas?


Has the carb been puled off for a rebuild? If not sounds as though the floats may be out of adjustment or malfunctioning. Also a good kit will help it run better. You'll need the numbers on the carburetor to get the kit. There is either a tag or embossed area on where you can find these numbers. Dodge/Chrysler used Carter branded carbs in the past yours may still be one.

Edelbrock 1406 3 years old on a Chevy 350 corvette. Starts and runs great when cold but when it heats up to running temp. and I shut off the engine it will not start!! Has great spark,compression,and fuel....


Check the choke and make sure that the choke is all the way open when hot. The choke should only be closed when cold. The choke can be adjusted on the side by loosening the 3 screws and wathcing the butterfly valve.

1954 CORVETTE,3 CARTER YH CARBS, SET FLOATS @ 3/8 '' with a 2'' drop to bottom of float. Engine runs fine, but carbs leak gas freely upon shutting engine ''off''. Why? and how can this be fixed?


Check the needle and seat in the carbs, sounds as if the needle is not seating allowing gas to flow till pressure in the lines drop. Since bowl is full the gas will force its way out any place it can. Usually a gasket. Good luck!! Hope I gave you an idea of where to look.

My 1983 cutlass supreme keeps flooding out. It wont even start after sitting awhile, carburator fills up with fuel, what can be causing this?


Hello!


if you have a carbuerator unit on her, i assume you a refering to the fuel overfilling the bowl and flooding oiut after vehicle is shut off. this can be caused by a worn or dirty needle for the float, or possibly the float itself has ruptured and is partialy submirsed allowing excess fuel to enter the fuel bowl. i believe you may have a 307 or 260 engine that came with a rochester 2 barrel carb. there are unly a few screws on top of this carb and is quite simple to check...just be careful to place all pieces back in same position removed from...although with that age, the gaskets will likely tear when taking apart. it may be worth your while to check into a complete replacement from NAPA. anyways, once the 4 or 6 screws (cant remember) are off from top of carb (i suggest having the carb removed from engine as if you drop a screw into throat of carb and the engine ingests it..its bye bye engine)...the float will be exposed..carefully lift it out paying attention to the needle position once out...be carefule to not bend the tang that needle hangs on as this is you float depth that sets the volume of fuel allowed in bowl. and shake it to see if fuel is inside float. if so, replace it..if not, you may be able to spray carb cleaner into the seat that float needle sits in and wash off the needle itself..reasseble and recheck performance..also it is a good idea to replace fuel filter when carb is off...i hope this help you...good luck!

ps your 4 thumbs up is much appreciated

Gas leaking out of a 1983 cordoba top of carburetor


Did the carb kit come with a new float? It sounds like the float level is not set right, it has a hole in it or the needle is not seating right. If the float is not set correctly it will hit on the carb body before it shuts off the fuel flow with the needle and seat. If the float has a hole in it it will fill with fuel and not float at the proper angle to shut the fuel off when the desired level is reached. Remove the top of the carb and inspect the float when closed it should be just about level with the top plate from the carb. Shake the float and see if you hear any liquid in the float. Also are you running a mechanical or electric pump? Mike
P.S. I myself have forgotten to install the needle in a carb rebuild.

Let me know how you make out.
