How to start a Shindaiwa C300 Trimmer when it won't start?
- SSteven BennettAug 5, 2025
If your Shindaiwa Trimmer engine won't start, there are several potential causes and solutions: * Ensure the ignition switch is in the START (ON) position. * Check the fuel. Refill with fresh fuel of the correct mixture (gasoline and Shindaiwa Premium 2-cycle Engine Oil (50 : 1 ratio)). * Inspect the spark plug. If it's fouled or improperly gapped, clean and re-gap it to (0.6 ~ 0.7mm). If damaged or the wrong size, replace it with a NGK BPMR6A. * If there's excess fuel in the cylinder, crank the engine with the plug removed, replace the plug, and re-start. * If the fuel filter and/or vent are clogged, clean them. * Also, make sure the spark plug is not loose; tighten it and re-test.
