The Air/Fuel Monitor consists of an oxygen sensor and a calibrated electronic display. Install the oxygen sensor as per the instructions in the exhaust pipe and connect the electronic display. When the engine is running, the actual air/fuel ratio is continuously displayed. Directly indicates air/fuel ratios from approximately 12 to 15:1. Use it to guide carburetor adjustment and jetting or to improve ignition spark advance curves. Works great for RVs or any application where frequent altitude and climate changes are encountered. Use as a tuning tool. Not recommended for use with leaded fuels or alcohol. Kit includes oxygen sensor/bung, harness, display unit, installation instructions and example calculations on how to jet carburetor for best power.
