I want to use one to tune a mower, tiller & chainsaw.** A: Just wrap the wire around the spark plug wire and that’s it, this tach comes with instructions how to calibrate it for one or two cylinders. **Q: I purchased this. says for 4 stroke engines.has to be attached near coil. i cant to that. will it still work on my champion 3500 generator?** A: Yes I have one on my champion generator works great ## Frequently Bought Together - Hardline Products HR-8061-2 Hour Meter/Tachometer for up to 2-Cylinder Engines - WEN 55201 Magnetic Oil Dipstick for Inverter Generators (compatible with WEN, Yamaha, Predator) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/2719723-hardline-products-usa-hr-8061-2-inductive-hour-meter-tachometer](https://www.desertcart.jp/products/2719723-hardline-products-usa-hr-8061-2-inductive-hour-meter-tachometer) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-19*
