Carburetor KEIHIN CVK 2600A Constant Pressure, Art. CM129213

This original KEIHIN CVK 2600A constant pressure carburetor is the ideal replacement part for restoring optimal engine performance and smooth throttle response. It is excellently suited as a high-quality OEM replacement for various 125cc and 150cc 4-stroke Piaggio Leader engines (e.g., installed in Vespa ET4, LX, Piaggio Fly, Liberty, and other models). Thanks to its reliable constant pressure design, the carburetor ensures a consistently optimal fuel-air mixture, smooth idle, and a noticeably even power delivery across the entire RPM range. The carburetor is delivered fully assembled, including an e-choke (electric choke).

Installation and Maintenance Tips

• Installation and Tuning: The carburetor is delivered pre-assembled. When installing, check the secure fit of the intake rubber and use suitable hose clamps to avoid air leaks. Depending on the air filter and exhaust system, fine-tuning of the mixture adjustment screw and idle screw after warming up the engine is recommended.

• Maintenance and Care: Pay attention to clean fuel and an intact fuel filter. For prolonged periods of inactivity, it is advisable to drain the gasoline from the float chamber to prevent clogging of the jets.
