The spark plug gap for Honda HRX217 lawn mowers is 0.030 inches (0.76 millimeters).
Engine and plug compatibility
The HRX217 line uses Honda’s reliable small-displacement engines, commonly the GCV160 family. For these engines, the recommended spark plug gap is 0.030 inches (0.76 mm). When selecting a replacement plug, many owners use standard NGK options such as BPR6ES or BR6ES, or their equivalents, ensuring the gap is set to the specified measurement. Always confirm the exact specification for your model year and regional version in the owner's manual or Honda parts listing.
Plug types and gap guidelines
To help ensure reliable starting and smooth operation, follow these guidelines for plug type and gap. The information below applies to most HRX217 units, but variations can exist by model year or region.
- Spark plug gap: 0.030 inches (0.76 mm).
- Approved plug types: NGK BPR6ES or BR6ES (or equivalents) are commonly listed as compatible with the HRX217’s engine.
- Gap setting method: Use a precise feeler gauge to verify 0.030 inches and adjust the ground electrode carefully if necessary.
Concluding: For best results, match the plug to the engine type and maintain a 0.030-inch gap; consult the manual or Honda parts diagrams if you’re unsure about your exact model version.
Steps to replace and gap the spark plug
When replacing the spark plug, follow these steps to ensure it is correctly gapped and seated. Always refer to the manual for torque specifications and installation details specific to your model year.
- Remove the spark plug boot and use a spark plug socket to extract the old plug.
- Check the plug gap with a 0.030 inch (0.76 mm) feeler gauge and adjust the ground electrode if needed.
- Install the new plug and tighten to the manufacturer’s recommended torque, avoiding over-tightening.
- Reconnect the boot and start the mower to verify proper operation.
Concluding: Keeping the spark plug gap at 0.030 inches is essential for dependable starts and efficient combustion on the HRX217. If you’re using a plug type other than NGK BPR6ES/BR6ES, double-check the gap against the manufacturer’s specs for that plug.
Summary
In short, set the spark plug gap to 0.030 inches (0.76 mm) for Honda HRX217 lawn mowers, typically using NGK BPR6ES or BR6ES plugs or their equivalents. Always verify with your specific model’s manual or Honda’s official parts listings, as there can be regional or year-to-year variations. Regularly inspecting and maintaining the correct gap helps ensure easy starts and optimal mowing performance.
