When diagnosing poor starting behavior, erratic engine running, misfiring or backfiring, or engine stalling, check for dirt or moisture in any of the plug connections of the engine electrical system. Where necessary, clean plug connections with compressed air and a hot air blower.

Check also for cleanliness of plug connections when removing and installing engine.
