3K Carburetor

The Certified Machine & Design 3K carburetor offers a reliable solution for smaller displacement engines, specifically the Suzuki Samurai 1.3L and Tracker 1.6L 8V. This is not a standard off-the-shelf carburetor; each unit undergoes a rigorous inspection and testing process by Certified Machine & Design. The process begins with a thorough inspection for any debris, incorrect float settings, potential leak points, damaged gaskets, or misaligned linkages. Recognizing the common weak points in these carburetors, Certified Machine & Design then installs each unit on their shop vehicle, 'Lab Rat,' to meticulously adjust cold idle, hot idle, and fuel settings. They ensure the idle circuit is solely responsible for keeping the engine running at low RPMs. The fuel screw is set for maximum vacuum, with final micro-adjustments made using an Innovative Air/Fuel Wide Band O2 Sensor. The idle is then set to 800 RPM, followed by a real-world 4-mile test drive to confirm immediate starts, correct idling, and responsive throttle blips without stumbling. This meticulous testing means that not all carburetors pass Certified Machine & Design's quality control. Units that fail are set aside for a complete overhaul, addressing manufacturing errors such as misdrilled holes or missing components. Approximately 45% of units fail this process, ensuring that when you purchase from them, you receive a carburetor that is ready to perform right out of the box. For those replacing a Weber carburetor, it is recommended to purchase the Weber Studs and Nuts separately.
