SOURCE: need setting for carb. adjuster on bottom of carb

Turn the adjusting screw all the way in until it LIGHTLY seats. Now back it out one and one half turns. Do the same adjustment for the throttle screw on the right side of the carb. You are now back to the stock factory settings.

Could you take a moment and rate my answer? Thanks!

SOURCE: floats not set

Float tabs come set flat to surrounding plate, bend up to decrease level and down to raise level. Raised level too much and you risk fuel overflow on sustained inclines and too low a level and you will lean out at high revs and damage valves/piston real quick. There is no set level to speak of, but better to err on the side of losing a bit of overflow. The overflow drains from the carby via a plastic hose from just above float bowl flange.
Cheers.

SOURCE: mikuni carb for jet ski

Mikuni carburetors, commonly installed on motorcycles ranging from small single cylinder dirt bikes to V-Twin motorcycles, have a plastic float to regulate fuel consumption. The float in the Mikuni carburetor sets the height of gasoline that rests inside the bowel. If you set the float too high, you risk overflowing gasoline from the carburetor and if you have it set too low, you risk running out of gas when you have your motorcycle at higher throttle positions. Mikuni has specific measurements for the setting the float levels.

  • Remove the four screws that hold the float bowel onto the bottom of the carburetor. Pull the float bowl and float bowl gasket off the carburetor. Use a Phillips screwdriver to remove the float bowel screws.

  • 2

    Place the carburetor upside down and let the float rest against the float needle. Do not touch the float at this time.

  • 3

    Measure the distance between the gasket surface located on the bottom of the carburetor to the edge of the float. On a 24 mm Mikuni card, the distance between the gasket surface and the float should be 1 inch. On a 20 mm Mikuni carburetor it should be 7/8-inch. Use a precision ruler for this.

  • 4

    Bend the metal tab on the float that rests against the float needle. Bend it towards the float needle if the measurement is shallow and away from the needle if the measurement is too much. Use you finger to bend the tab. If you cant bend it with our fingers, use a pair of needle-nose pliers. Make very small adjustments to the metal tab and then recheck the measurement.

    How to adjust carb float level ?

    Carbs off and upside down measure the distance between the top of the float and the part of the carb where the float bowl gasket goes ,with the gasket off.there will be measurement in the manual and it will be plus or minus a millimetre.you adjust it by bending the metal tag that pushes on the float needle that's joined to the float , unless it's made of plastic then it can't be adjusted.

    STARTS IDLES BUT WONT REV UP,ALREADY CLEANED CARB ANY OTHER SUG

    You cleaned the carb; did you rebuild it? Did you put in new throttle springs and adjust the needle jet properly... the keeper ring placed on the correct groove? Did you put a new float in and then adjust the float travel properly? If you didn't do these things, then you aren't finished yet. All these things make a difference. If you need to put a new float in, be careful as the metal tab is easy to break off when bending it to correct specs.

    I have a 1981Suzuki gs550l Fule runs out of the back of the carbs Ive replaced the petcock The needles and seats Adjusted the floats to spec and cleand everything very thurowly and fule still flows right...

    Float valve seats have o ring seals on some carbs,
    check those. Float level must be set correctly
    or floats will hit the carb body before needle closes.
    Floats must move easily up and down.
    Carb body air vent passages must be clear.

    What is the hight of the float in the carb

    if the exact height is not known , a good rule of thumb , is to tilt the carb on its side (with float bowl off) and watch the float to see when its just begins to push on the float valve .... at that point the floats should be level with the sealing face that the bowl bolts up too ....if not , bend the little metal tang till it sits level ..... hope this helps

    How do i adjust carb float and what are the specs

    you can adjust a float by taking the little pan off of it and just bending the stop that goes to the needle valve , usually you do not have to do this to carbs , what is the problem you are having ,if to much gas is coming out , you needle could be stuck , I tap it with a little hammer but lightly to free it up , good luck if you want the specs you can goto their site and will find it there or buy a manual of your bike , ebay is a good place to find one , good luck

    CARB ADJUSTMENT

    The Float adjustment usually involves carefully bending a tab against the needle valve where the fuel enters the float bowl. Since the float, "floats", there is no external adjustment. The float should close the valve at a specific height, and open as the fuel level drops, thus controling the level of fuel in the bowl, which in turn controls the amount of fuel being ingested by the carb. As for cleaning, any over the counter fuel system cleaning additive will help with that, from any auto parts store.

    750 holly carb put a holly fuel pump floods won't run idle adjusted the float all the way down still floods it on a 5.0 motor

    make sure that your fuel pump is rated for the same pressure as your carb. if you bought it as a package deal than it probably is but unlike fuel injected vehicles that have a pressure regulator the fuel is constant flow in a carb.

    Just need the height setting for the floats the

    YOU CAN ADJUST FLOATS WITHOUT SPECIAL TOOLS. ALL YOU NEED IS A FOOT LONG PIECE OF CLEAR TUBING, SIZED TO FIT THE BOWL DRAIN. SET FLOATS AS CLOSE TO WHAT THEY WERE WHEN YOU REPLACED IT. INSTALL THE BOWL AND PUT THE TUBE ON THE DRAIN. OPEN THE BOWL DRAIN SCREW WHILE HOLDING THE TUBE UP BESIDE THE CARB. WHEN YOU GET THE TUBE BESIDE THE CARB ASSY., THE GAS IN THE TUBE SHOWS YOU THE EXACT LEVEL OF FUEL IN THE BOWL. FROM THIS YOU CAN MAKE ANY ADJUSTMENTS NECESSARY FOR CORRECT LEVEL. THE LEVEL SHOULD BE RIGHT BELOW THE PLANE WHERE THE BOWL MEETS THE CARB BASE.
