Linkstyle Small Engine Tachometer, Digital Tachometer Tach Gauge Reset Function Equipped with Clip, Inductive Hour Meter for 2 Stroke 4 Stroke Small Engine for Cropper Generator Lawn Mower RV

What It Is

A digital tachometer that measures engine RPM and tracks total run time (hour meter) for small engines. Designed for 2-stroke and 4-stroke engines on lawn mowers, generators, croppers, RVs, and other outdoor power equipment. The inductive clip picks up spark plug pulses—no direct wiring needed.

Fitment & Compatibility

• Engine type: Works with any spark-ignition small engine (gasoline, 2 or 4 stroke). Not for diesel engines.
• Attachment method: Clips around the spark plug wire. Must have accessible spark plug wire with enough slack to fit the inductive clamp.
• Display: Universal fit—no brand-specific mounting. Adhesive-backed or zip-tie mount to any flat surface near the plug wire.
• Battery: Uses a CR2032 coin cell (included). Check that the battery tab is removed before use.
• Measurement range: RPM 0–99990, hour meter counts up to 99999.9 hours. Works with single-cylinder engines only (not multi-cylinder).

Key Things to Know

• Installation: Very easy—just clip the inductive pickup around the spark plug wire (closer to the plug end is better). No tools required beyond a screwdriver to mount the bracket.
• Accuracy: Acceptable for tuning carburetors or setting idle speed, but not lab-grade. Expect ±1-2% deviation on RPM readings.
• Reset function: A small button on the back resets the hour meter. Be careful not to bump it accidentally—you can lose all run-time history.
• Battery life: Claimed 1–2 years of typical use. The unit has no backlight, so it’s hard to read in direct sun or low light.

Should You Buy It

Buy this if you need a cheap, easy way to set idle RPM, check max RPM under load, or track engine hours for maintenance intervals. It’s perfect for hobbyists tuning a mower or generator, but skip it if you need laboratory precision or a backlit display—step up to a professional tachometer for that.
