What is the float adjustment on the carb I know how I just need the measurement on it

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.

If you can't find the measurement, just turn it upside down and adjust the float parallel with the surface where the bowl fits.

if the float is attached to the top of the bowl (cover) the invert the cover and measure the distance from the cover to under the float. There will be a dimension and it is measured by the use of a twist drill that is that dimension. Bending the tab on the back of the float will be the adjustment.. Some have a plug in the side of the bowl that you remove and adjust the needle and seat height until the fuel is at the threads of the hole.

Pull the float bowl and float bowl gasket off the carburetor.
Place the carburetor upside down and let the float rest against the float needle.
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.
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 a pair of needle-nose pliers, making very small adjustments to the metal tab and then recheck the measurement.

Float height is not related to time. This is a very technical area (carb adjustment) best left to the pros who have the skills, knowledge and equally important, the measurement tools to properly adjust a carb. Time is an entirely different thing.

float level is usually per bike. you can try to start at 16mm give or take 1mm this is the setting for a 1989 kdx 200/220. it is measured from the bottom of float to the mating surface just touching needle. the best way is a service manual or owners manual should tell you. You can play with them a little by changing the measurements you can richen or lean the fuel a little, example 18mm would be leaner, and 14 would be richer.

Sticking floats or worn float valve needles or incorrect float height, tap float bowls to see it overflow stops (sticky float), remove and clean float bowls and fuel inlet passage with carb cleaner and compressed air, check float valve for wear to the rubber tip. Reset float height by slightly bending the metal tab on the float to adjust the closing height of the valve measure from the carb bowl mating surface to the top of the float when fitted then re adjust 1mm at a time higher untill fuel doesnt over flow.

the floats in the bottom of the carb need adjusting the are to low




When setting the float level be aware that the spring loaded bumper on the fuel inlet needle valve may have a tendency to compress under the weight of the float assembly which will skew your measurement. Before you obtain your measurement you'll need to make sure that the float assembly tang just barely makes contact with the spring-loaded bumper. Sometimes it is easier to hold the carb body at a 45-degree angle to avoid compressing the spring in the fuel inlet needle.




If you find that your measurement does not match your float level spec then you can carefully bend the float assembly tang to achieve your desired measurement. Be sure to recheck your work, and if you feel confident that your float level is spot on then you can reinstall your carb and get back to riding.

You describe a problem with either the float or the float-needle and seat. If the needle is not seating then the gas flows past it. If the float has a pin-hole leak, then it will fill with gas and sink.
On some bikes you can remove the carb bowl without removing the carbs. If so, slide the hinge pin holding the float to one side and remove. The float will drop straight down. Catch the needle since it is now loose. Unscrew the needle seat with a socket.
Clean all metal parts in carburator cleaner...do not get carb cleaner on any rubber part. Shake the float and listen for gas inside or see if it floats in water.
Test the needle seal in the seat by blowing gently thru seat. Needle must seat completly with very little pressure holding the needle in the seat.
Re-assemble with new bowl gasket if damaged. A carb rebuild kit ($35) might be available for 1973 carb and contains all new parts instead of cleaning. Kit might even contain new float and float adjust guide.
Avoid adjusting float level if re-using the old float. If using new float, temporarily install old and measure distance to carb body. Install new and match this measuremnt. Bend tang to adjust.

Good luck,

Hi,
Your float levels should be 15.5 mm for the 83. This measurement is from the bottom of the carb base to the bottom of the float with the needle gently resting in the seat. I have found that tilting the carb assembly until the needles lightly seat works the best.
When adjusting the level height with the assembly completely inverted, there tends to be too much pressure from the weight of the float onto the needle resulting in an inaccurate measurement.
If you need any more help, let me know.
