How To Adjust My Mikuni Jet Ski Carb

It is very difficult to run the equipment if the owner has not taken the time to learn how to adjust my Mikumi Jet ski carb. This is the key to combining air and fuel so that the system can work properly in the Japanese models such as Kawasaki, Yamaha and Honda. 

The process is best accomplished with the aid of the following materials:

  • Screwdrivers with a flat head
  • Normal Phillips head screwdrivers
  • An adjustable wrench
  • Protective gloves
  • Protective eye equipment
  1. Adjusting the air filters on the Mikumi Jet ski carb: The operative needs to remove the air filter from the mounting with the aid of the flathead screwdriver. Debris must be removed from the filter before it is returned to its slot. A replacement should be made if the air filter is corroded or damaged in any way.
  2. Air adjustments on the Mikumi Jet ski carb: The air screw will need to be located using the Phillips head screwdriver. This is normally at the back of the carburetor. The screw is turned right to reduce the air entering the carburetor. The end result is a powerful engine that consumes fuel faster.
  3. Adjustment of the Mikumi Jet ski carb: The pilot jet will need to be located underneath the air screw with the aid of the adjustable wrench. This is meant to ensure that the right amount of fuel is entering the carburetor. A right turn reduces the weight and a left turn increases the fuel according to the specifications of the owner.
  4. Adjustment of the throttle slide valve on the Mikumi Jet ski carb: The throttle slide valve regulates the combination of air and fuel. The settings are numbered. The high settings increase the power of the engine. This is achieved by allowing greater amounts of fuel and air to enter the engine.
  5. Adjustment of the needle for the Mikumi Jet ski carb: The adjustable wrench will enable the user to loosen or tighten the need according to the specification. This needle should correspond to the throttle slide valve in order to regulate the engine power.
  6. Adjustment of the throat valve on the Mikumi Jet ski carb: The Philips head screwdriver will enable the reader to adjust the choke valve through tightening or loosening. Power will be increased when the choke valve has been loosened.


It is imperative that the user takes note of all the factory settings before the adjustment so that they can be reused when necessary.

It is always good to wear protective equipment when undertaking this process.
