I need to know what's the float level measurements for my 1993 gsx 750 carburetors. I want to adjust my floats but don't know the measurements...

You will need to remove the float bowl. Some carburators will have a carbon coated plastic float, if the coating gets scratched, the float will sink, causing your problem. If it's a hollow metallic float, it can get a hole in it, and sink. If the float is good, then the rubber seal that the float pushes up when the float bowl starts to fill with gas is leaking. This can be caused by debris between the valve seat and the valve, or the rubber is cracked or hardened. In any case, usually there is 4 screws on the rounded bottom of the carburators, remove them and you will see the float. If it doesn't float in a bowl of gasoline, it needs repaired or replaced. If the small rubber seal the float moves is cracked or deformed, it needs replaced. There may just be a tiny bit of debris between the float valve and the seat that needs removed. Good luck. None of this is very expensive.

The float level and float drop are both measured with the gasket in place. Having said that, here are the following measurements.

Float level is measured between the edge of the float seam and the formerly mentioned gasket. This measurement is 1/2" on a 2 bbl. and 1 21/64" on a 4 bbl. for the primary and 1 3/8" on the secondary.

The float drop is measured from the bottom edge of the float as it's hanging from the pivot, to the gasket.

The 2 bbl. is 1 29/32" and the 4 bbl. is 1 19/32" on the primary and 1 3/16" on the secondary.

These measurements and instructions come from a 1965 Chilton Auto Repair Manual as that's the only reference I have.

Hope this helps.

- 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).

Hi,
That means you only adjusted the float and did not check the needle stopper/valve that stops the fuel flow going into the fuel chamber.
Check the valve if it needs to be replace or some dirt might hampers the sealing of the needle.
PLEASE DON'T USE SILICONE ON CARBURETOR( silicone dissolves when mixed w/ gasoline )!
Use a 3bond sealer.
Hope that helps you out!

This is from a factory manual, please rate my answer. Thanks >>>

vapor lock? float level ? main needles to low

YOU CHECK FLOAT LEVEL LOOKING AT THE SIGHT GLASS ON THE RIGHT OF THE CARBURETOR.FUEL LEVEL SHOULD ALIGN WITH THE DOT ON THE SIGHT GLASS.IF THE LEVEL IS ABOVE OR UNDER THE DOT THE CARBURETOR HAS TO BE DISASSEMBLED.TO SET FLOATS REMOVE AND INVERT THE AIR HORN UNTIL THE FLOAT ARM JUST TOUCHES THE NEEDLEVALVE OR THERE IS ABOUT 0.1 mm OR 0.004 INCH CLEARANCE BETWEEN THEM.MEASURE THE DISTANCE BETWEEN THE BOTTOM OF THE AIR HORN GASKET INSTALLED.AND THE CENTER OF THE BOTTOM OF THE FLOAT.THE DISTANCE SHOULD MEASURE 36.4 mm 1.39 - 1.47 INCH. ADJUST BY TURNING THE NEEDLE VALVE SEAT.BE CAREFUL NOT TO ALLOW THE VALVE SEAT TO PROTRUDE FROM THE SEAT ATTACHING BOSS.WHICH WOULD ALLOW THE VALVE TO FALL.IF THIS IS THE CASE BEND THE FLOAT ARM SLIGHTLY UNTIL PROPER CLEARANCE CAN BE OBTAINED.WHEN CARBURETOR IS INSTALLED CHECK FLOAT LEVEL BY LOOKING INTO THE CARBURETOR FLOAT SIGHT GLASS I MENTION IN INFORMATION ABOVE.IF YOU HAVE A 1487cc AND 1600cc CVCC MODELS WITH THE KEIHIN 3 BARREL CARBURETOR.THIS WOULD DEALERSHIP JOB.THIS TYPE IS HARD TO ADJUST.

ohh budy it sounds like the floats need adjusting are you able to take carbs off??

you put it on the float base and allow the float to drop down and read the gauge where the float is read the top of the oppiste side where the float is hinged.
