This sounds like your have rust in the tank. Drain the fuel and check that the fuel filter on the petcock in the tank is still there. If your cycle has an in line filter replace it. If not, you may want to add an in line filter. I would also try a small dose of fuel system cleaner in case you purchased some gelled/gummy fuel. If this does not not solve the problem you may have to dismantle the carbs and inspect the needles for wear. If the tips are worn or the sides show wear, worst case scenario, you will have to replace the needles.

1996 750 katana suzuki how to set floats?

- Now days some carburetors are produced which are fixed and no adjustment is provided.The float is made up of whole plastic like material.
Some floats have the copper/metal notch for the adjustment of fuel level.
- Take the carburetor assembly out.
- Remove the fuel bowls.
- Place the carburetor assembly with the floats upward towards yourself.
- Float level gauge and active data list (taken from the workshop manual) is required to carry out the adjustment. But you can simply adjust the float level correctly without any gauge.
- Hold the carburetor assembly at your eye level in such a way that the carburetor No. 1 is in front of you. Behind is No. 2 carburetor, then behind is No. 3 and then the No. 4. Or we can say that the carburetor No. 1 hides the carburetors 2, 3, and 4.
- Examine carefully the floats of all the individual carburetors be parallel to the surface of the carburetor where the float bowl face is seated and tightened.
- Adjust the float level by bending the float notch towards the needle valve (to decrease the float level and to raise the float) or away from the needle valve to increase the float level (to lower the float).

Flooding out

Three things cause this....
1. Debris between the float needle tip and the float needle rubber seat.
2. A very very very dirty air cleaner.
3. A fuel float assembly that the float has filled with fuel and is too heavy to float up with the fuel level.
My bet is there is dirt in the float needle seat.
remove the float bowl
remove the float hinge pin and drop the float (Shake the float gently checking to make sure there is no internal fuel inside the float.) If there is fuel in the float replace it.
remove the main fuel line

Spray carb cleaner UP into the float needle hole so that the debris will wash out of the the float needle seat. Next spray carb cleaner from the main fuel line connection through the float needle seat.

Reinstall the main fuel line.
reinstall the float needle and float as one unit.
Turn on the fuel selector...
raise the float gently until it is just level. Fuel flow must stop. If it does not stop change the float needle and seat.
Reinstall the float bowl.
Test for leaks..
Start generator. Task complete.

To much fuel! Boggs out! crimp fuel lin e to starve engine of gas and runs great?

Either the float level is too high or there is debris in the float needle seat. This causes the carb to overflow while running. The fix is:
- Remove the main fuel line with the fuel selector off of you have one.... or pull the line and plug it off / keep the end above the fuel tank then
- Remove the float bowl from the carb.
- Pull the float pin and remove the float and float needle (INSPECT float needle rubber tip for damage or dirt... any damage replace float needle and seat.)
- Spray carb cleaner into the main fuel supply hose / manfold fitting on the carb. Your removing any debris that night be in the float needle seat area
- Spray carb cleaner in all open fuel jet passages without dis-assembly of the carb.
- Reinstall the float needle and float (Float pin too!)
BRIEFLY reconnect the main fuel line
GENTLY lift the float to level.... (Incoming fuel flow MUST stop) Lower float.. (fuel must flow)
If the fuel flow does not stop with the float level.. you must replace the float needle snd seat. After needle and seat replacement if fuel still does not stop with the float level the tab where the float needle is will have to be bent UP no more than 0.010 at a time and then re-test flor fuel stoppage with float level. Adjust tab as necessary to get the float level correct.
- re-assemble carb
- test... running and static.

My TZR 250 3ma, leaks fuel from the carburators, I had them cleaned and the float levels resetted. On the fuel tap if it is on or on reserve it gushes out the fuel. Can the tap be the problem and is there...

The tap is not the problem, it is working as it should. The problem is that the float needles are not shutting off the fuel as they should. Turn the gas off then remove the float bowl on one carb and check for trash in the bowl. Turn the gas back on while gently lifting the float. Now lower the float. The fuel should flow when the float is lowered and stop flowing when the float is raised. If it still flows with the float raised, turn of the gas then check to see if the mechanic forgot to install the float needle by removing the pin that mounts the float/needle assembly. Most carbs attach the float tang to the needle with a small clip. Is the clip missing? The needle can get out of position and not close properly without it. The float should be light as a feather and nothing inside rattling around. A float that doesn't float will never shut off the gas. If the float is good, disconnect the gas line at the carb then get a can of carb cleaner with a "straw" to direct the spray and stick the straw into the opening where the needle goes and spray into the hole. Trash may be holding the needle open. The spray should clear the trash out. If the float floats and there is no trash holding the float open and the needle kills the gas, the floats are way out of adjustment. Below is a generic float assembly. Please take a moment and rate my answer. Thanks! tombones49_45.gif

When i park my 78 xs 650 with the kickstand for a bit, when i lean it back up level gas comes out of the carb and down through the air cleaner box. Whats this?

The float level is too high or the float valve is being hung open by dirt or fuel varnish. First, turn the petcock to the 'off' position and then drain the gasoline from each float bowl by loosening the drain screw on the bottom. Close the drain screws and turn the petcock back on. Check to see if the problem is still there.
If so, then the float bowls will have to be removed and the float valves cleaned and inspected for wear. Also, take each float and shake it while listening for any fuel that may have leaked inside. Any float that has gasoline in it must be replaced. Upon reinstalling the float valves, check to see that the arms on the float are parallel to the float bowl gasket surface just as the float contacts the float valve. This is the correct float level. Adjust the bendable little metal tang on the float to achieve the correct float level.

Just bought a 82 xj650. It has some flooding on the right carb. any suggestions? Gas comes out the right side exhaust, also dies after running about 10 to 15 minutes.


1.Remove the Float Bowl, (Turn gas off first), and clean the crud out of the bowl. (Bottom of the carburetor)
There is a brass nut in the middle of the float bowl, which is on the bottom of the carburetor.
There is a fiber, or brass washer on that bolt. DON'T lose it! (Turn it to the left)
The brass bolt, (Main Jet Plug), goes through the float bowl, and into the Main Jet.

Remove the float, (Carefully! If it's a plastic designed float, Don't nick it with your fingernail/s. Also make sure it isn't soaking up gas. If so, {You'll know!}, replace it)

A.DON'T let the float needle valve fall out, when you remove the float! The Float Needle is attached to the float, with a small 'hair spring' clip.

B.DON'T lose the tiny, 'hair spring' clip, that attaches the float needle to the float.
Observe VERY carefully how this tiny spring clip goes on the float, ->Before you remove the float pin. (The float rotates up, and down, on this long round pin) It has to be put back the same exact way)

Handle the float with extreme care. It is set to a certain height. The measurement goes from the bottom of the carburetor body, (Where the side of the float bowl touches), to the top edge of the float.

The top of the Float Needle has a groove cut around it. That 'Hair Spring' clip I described above, clips in this groove. The other end of this 'Hair Clip', goes around a flat area that extends out of the side of the float.
Once you get the float bowl down a bit, you'll see what I'm referring to above.

C.The Float Needle Valve is made of metal, and has a Neoprene, (Like rubber), tip on the end. The Neoprene tip is cone shaped. A light little ring mark on the Neoprene tip is okay.
If the tip is broken, or mushed out, the Float Needle Valve is no good.

More than likely you just have crud in the float bowl, and it is also down in the Float Needle Valve Seat.
(The Float Needle Seat is a brass cylindrical shaped piece. It has a tapered hole inside, down at the bottom. Fuel, {Gas} comes through this tapered hole, and the Float Needle Valve regulates how much. The float raises, which raises the float needle valve. Fuel comes through the tapered hole. The float drops, which lowers the float needle valve, and stops fuel from coming through the tapered hole, and into the float bowl)

After time, the bottom of your gas tank develops rust, from moisture in the gasoline.
Dirt also finds it's way into a bike's gas tank. Also the additives in gasoline accumulate after a while.

If you do not have an inline fuel filter, I advise you buy, and install one. This way you change the fuel filter element, and do not have to tear the carb/s down again.

I am getting fuel leaking from the bottom of the carb and I have adjusted the screws on the bottom of the carb but it is still is a 1997 flstf fatboy

Carburetors have a Float Bowl on the bottom. This float bowl has a small amount of fuel, that the carburetor uses. (The float bowl's amount of fuel, is replenished from the gas tank. The fuel is gravity fed from the gas tank, through the Fuel Line)

The float bowl has a Float Needle inside. The float needle is attached to the Float. The Float resembles a thick doughnut. On one end of this doughnut, is a flat piece of metal shaped like a U on the end. Looking at this -> U shape, there are two holes at the top. There is a metal pin that goes through these holes, and the pin is attached on it's end's, by the main body of the carburetor.

The flat metal U shape, and the metal pin, works together to form a type of hinge, allowing the float to pivot on it.
Where the U shaped hinge is attached, the float needle, clips to it.

The float needle has a tapered neoprene tip, and sits in a Float Needle Seat. This seat is a barrel shaped piece of brass, and has a tapered hole at the bottom. Fuel comes up through this seat, and the float needle regulates how much fuel can come in.

As the float drops down, it draws the float needle out of the float needle seat, and fuel comes in. As the float bowl fills with fuel, the float rises, and pushes the float back up, also pushing the float needle back into the float needle seat, cutting off the flow of fuel.

There is a specified height of the float, in relation to where the float sits in the float bowl. If the float sits too high, the float bowl fills up with fuel, and overflows. This overflow goes through an Overflow Tube, on the carburetor.
(If the float sits too low, the engine starves for gas)

A LOT of times, crud builds up in the gas tank, makes it's way through the fuel line, and gets into the float bowl. It can get in-between the float needle, and the float seat, thereby flooding the carburetor out, and fuel comes out of the overflow tube.

The float bowl is also attached to the carburetor with a brass main jet nut. At the bottom of the float bowl, this will look like a brass head of a bolt. Under the brass head is a small O-ring. This can leak. First step is too insure this is tight. (Do Not Over tighten! This is part of the main jet, and is expensive! It's Brass)

Where the outer part of the float bowl itself, attaches to the carburetor, there is another O-ring.
A large one. This O-ring, like the main jet O-ring, can deteriorate over time. Additives that gasoline has in it, heat from the engine, and heat from the sun does this. Plus just age. Neoprene breaks down after time.

It could also be that the neoprene tip of the float needle has broken down.

You indicated you adjusted screws on the bottom.
These are the Main Jet, and Idle Jet -> Air Mixture screws. All they adjust is how much air goes through these jets.
The amount of fuel going through, is predetermined by specific passageways, that are drilled through the main body of the carburetor.

This only comes into play when the engine is running. With the engine off, and fuel leaking out, you have crud under the float needle, or one or more of those O-rings has deteriorated.
