Measurement Method:

  1. Adjust the engine's idle speed according to standard data and turn off the engine.
  2. Attach the rubber vacuum tube to the pressure gauge and secure it with the elastic clamp.
  3. Using the special threaded copper joint, screw it into the carburetor thread, ensuring a proper fit. Connect the other end of the rubber vacuum tube to the copper fitting.
  4. Confirm the pressure gauge rubber vacuum tube is connected to the carburetor cylinder being measured.
  5. Warm up the engine, start adjusting carburetor synchronization, and fine-tune after refueling (accelerating) and returning to idle speed.
  6. Consult the vehicle's factory data sheet for carburetor negative pressure standards.


  1. Handle with care to prevent water, oil, dust, and debris from entering the rubber hose passage.
  2. Avoid impacts, high temperatures, humidity, and direct sunlight to maintain the instrument's integrity.
  3. Clean the meter with a soft cloth; refrain from using gasoline or solvents.
