Difficult Starting After Warming

Quick Check: Compare ignition spark when engine temperature increases.

Fix Suggestion: Check coil output again after reaching normal temperature.

Prevention Tip: Monitor recurring warm-start changes during regular hedge trimming.

Engine Stops During Operation

Quick Check: Check whether the spark disappears immediately after an unexpected shutdown.

Fix Suggestion: Trace coil wiring for intermittent electrical contact points.

Prevention Tip: Keep ignition connections firmly positioned against operating vibration.

Irregular Engine Firing

Quick Check: Listen for irregular firing during steady throttle operation.
