This Air Gap Setting Tool is a precision made replica of the original Johnson Evinrude OMC service tool 33499. Designed to accurately set the critical air gap between the flywheel and the sensor or stator charge coils. Proper air gap adjustment is essential for correct ignition timing, reliable charging output, and smooth engine operation.
This tool is specifically engineered for 2-cylinder OMC, Johnson and Evinrude outboard engines manufactured from 1978 through 2006. It allows technicians and DIY mechanics to quickly and consistently achieve factory air gap settings during ignition service, stator replacement, or routine maintenance.
Built for durability and repeatable accuracy, the 334994 air gap tool simplifies a normally precise adjustment process, helping prevent misfires, weak spark, and charging issues caused by improper sensor or stator positioning.
