The ignition coil air gap is the distance between the ignition coil and the flywheel. Maintaining the correct air gap helps ensure a strong, consistent spark for reliable starting and proper engine performance. An incorrect air gap can result in poor performance, a weak or no spark, or damage to the ignition coil.
Gas-Powered Products: The ignition coil air gap for all ECHO® gas-powered engines is 0.012–0.016 in. (0.3–0.4 mm).
Battery-Powered Products: Battery-powered ECHO® products do not use spark ignition and therefore do not have an ignition coil air gap.
