Hi Norberto Mora
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.

1977 GS750 Throttle slide height
When adjusting the throttle slide height on a 1977 GS750, the manual states that the slides should be set at .5-1mm above the top of the carburetor when they are opened wide open. The correct position to set the slide height is on the airbox side of the carburetor slide.
When the throttle slide is set too high on the engine side, it can cause the bike to idle high, as you mentioned. This is because the slide is not allowing enough air to enter the carburetor, which can cause the engine to run rich.
To adjust the throttle slide height, you will need to follow these steps:
  1. Remove the air filter and carburetor top covers to access the slides.
  2. Using a feeler gauge, measure the distance between the top of the slide and the top of the carburetor.
  3. If the distance is greater than .5-1mm, adjust the slide height by turning the adjustment screw located on the airbox side of the carburetor slide.
  4. Once the slide height is set, replace the air filter and carburetor top covers.
  5. Start the engine and check the idle speed. If it is still high, repeat the above steps until the correct slide height is achieved.
It's important to note that when adjusting the slide height, you will also need to make sure that the throttle cable is adjusted correctly, as this can also affect the idle speed. Additionally, when making any adjustments to the carburetor, it's best to have a professional mechanic to check it, as it could cause other issues if not set correctly.

Trx350tm2002model, runs fine after carburetor cleaning but is dying soon as rpm is increased What adjustments can I make to carburetor since I lost the adjustment setting to the fuel intake needle valve.
The carburetor actually is a mixing place for the air and fuel. If the mixture is not in appropriate proportions this issues surfaces. Many a times as the carburetor gets old, the jet, idling valve etc., may not function properly. My suggestion would be to replace the carburetor unit itself or try adjusting the air intake valve or air filter adjustment.

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).

Carburetor adjustments
The only thing that can be adjusted is the pilot screws (idle mixture) and those are capped from the factory for a reason. If it is not runing right the pilot jets are clogged or restricted. You need to pull the set clean them and apply black RTV silicone to the bots to get rid of vacuum leaks.

What is the walbro chain saw carburetor adjustment for a
There is no set adjustment on any chain saw. If it were that simple there would be no need for adjustments. The problem is that most equipment manufactured in the past 10 years can not be adjusted by the user. Carburetors are now equipped with either adjustment limiters which limit the adjustment to less than half a turn or with adjustment screws that require a special tool to make the adjustment. More than likely you will have to take it to an authorized dealer for those adjustments.

If you do have an adjustable carburetor, then gently close both needles and open each on 1 full turn. This should allow the engine to start and the final adjustments can be made at that point. If it still will not start then open each needle 1/8 to 1/4 turn and try again. If this still does not work then most likely your carburetor needs a good cleaning and a rebuild kit.
