The way to Troubleshoot an Electronic Ignition on a Chain Saw

Today’s chain saws rely on breakerless electronic ignition systems to make the spark needed to ignite the fuel mixture. These solid-state systems are dependable but can occasionally have problems. If you believe you’re experiencing ignition trouble, there are a few probable causes you are able to check out and fix yourself, saving a trip to the mechanic.

Spark Plug

The very first thing to check is that the spark plug. Inspect the ceramic insulator and the electrodes for breaks or cracks. Replace the plug if you find damage. Check the electrodes for reset and wear the electrode gap if needed. Then check for any broken or bare wires on the saw like the wires to your ignition “kill” switch. Check the plug boot and cable for cracks, breaks or splits. Replace any bad wiring you find.

Other Issues

Check for a terrible kill switch by disconnecting the switch’s cable and checking the plug for spark. Do so by unscrewing the plugin, holding it from the rubber boot and touching its threads to the engine metal whilst pulling the starter cord. When there’s spark at the electrodes using the kill switch disconnected, replace the evil switch. If the saw begins fine when trendy but won’t start when the engine is warm, the issue could be an ignition component that’s about to die. Also suspect a bad ignition module if you are not getting any spark and you’re sure the spark plug, its wiring and the kill switch are OK. Replacement is the only fix for a bad ignition module. Modules are cheap and widely available.
