Why won't my Shindaiwa BP35 engine start?
- RRobert BradleyAug 16, 2025
Several factors can prevent your Shindaiwa Brush Cutter from starting. It could be due to a loose or damaged spark plug, which you can try tightening or replacing. The spark plug may also be fouled or improperly gapped, so try cleaning and gapping it to 0.024 inch (0.6mm). Also, ensure the ignition switch is in the “I” (ON) position. Refill with clean, fresh unleaded gasoline with a pump octane of 87 or higher, mixed with Shindaiwa Premium 2-cycle mixing oil at a 50:1 gasoline/oil ratio. In some cases, the ignition system may be shorted, requiring you to replace the fuel filter or vent.
