Place the copper washer over the threaded portion of the plug and screw the plug back into the cylinder head. Tighten the plug with the appropriate torque. **Q: Does this work with 2-cylinder engines, or just singles?** A: It works with: 2 stroke: 1 cylinder / 2cylinder / 3cylinder 4stroke:1 cylinder / 2cylinder / 3cylinder / 4cylinder / 5cylinder / 6cylinder / 8cylinder /12cylinder/16cylinder 6 stroke:2 cylinder Some 4 stroke 1 cylinder engine is 1P1R,the setting is the same way as the 2 stroke 1 cylinder engine. **Q: How long are the wires on the temperature sensor ring cables? Only the length of the tach wire is shown.** A: The length of probe sensor wire is 58.5cm(approx.23.03 inches) **Q: How do I know which model to get? The connections look different.** A: we think your model is HM035A-TS003, the temp sensor can measure the engine temperature especially easy to put it into engine radiator. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for monitoring your small equipment *by on Reviewed in the United States May 28, 2026* Exactly as described and expected. Very Satisfied. Really great tool. ### ⭐⭐⭐⭐⭐ Best digital small engine tach out there *by on Reviewed in the United States September 26, 2024* The wires are really long and have a connector so you can disconnect them, they can also be turned off unlike other small tachs. only downside is the batteries dont last nearly as long, in my experience it needs to be replaced every 3-4 months. ### ⭐⭐⭐⭐ Price is fitting *by on Reviewed in the United States February 18, 2023* Cons:First time I unplugged the leads after test fitting, all three wires came out of the coupler. If you're familiar with R.C. cars, it has a connector much like a servo would have, except the wire aren't crimped into the metal parts. The only thing holding them to in place is piece of heat shrink that's around the case of the 3 wires and the plastic part of the connector. So I just soldered it back together, and it works. If you have a soldering iron, not too big of a deal, just slightly annoying. If you don't, well I suggest never unplugging the leads.There's also no mention in the instructions of where you should put the ring terminal for the heat sensor. A quick Google search will tell you it actually goes under the spark plug. The instructions are a little difficult to read, and obviously translated by someone who's first language was not English. Again, not a big deal, but I've never heard of a spark plug cap refered to as a "pencil style" as it's put. So to clarify that for anyone, 4 stroke engines need the yellow wire wrapped around the boot of the spark plug wire, 2 strokes need the yellow wire wrapped around the actual spark plug wire, just above the boot.Pros:Its a cool little gadget with a lot of functions. Perfect for my Craftsman DLT 3000 riding mower cause I can finally set the idle correctly and monitor the rpms. If you've ever owned a single cylinder OHV Briggs Intek engine, then you know that it's already living on borrowed time and it can get hot pretty quick from slightly low oil, or grass in the cooling fins, or its head gasket (which is seemingly set to self destruct if you just look at it wrong) and they throw rods, drop valve seats, and the rings will be gapped so huge you'll wonder if they're even the correct ones for the engine cause the piston slap is ridiculous. Air cooled engines also need the correct idle speed for the fan to blow enough air to keep it from over heating, you also dont want it to rev too high cause it will detonate. (Dont even get me started on the cam decompression lever, also a source of self destruction) so to me, having a tachometer is essential to keep one alive, so is a temperature reading to help you establish if the air/fuel ratio is good. Once i find out what that temperature is actually supposed to be for this engine, ill be set.Just buy the dam thing. Its cheep and it works. If you're handy, you can figure it out. ## Frequently Bought Together - Runleader Digital Tach Hour Meter,Engine Temperature Gauge,Alert RPM & Temp,Backlights Display for Lawn Tractor Compressor Generator Snowmobile Marine Jet Ski Pit Bike - HIAORS 50 inch Throttle Cable for CT200U Mini Baja MB165 196cc 5.5hp MB200 200cc 6.5hp Pit Bike Heat Warrior MOTOVOX MBX10 MBX11 Parts - YAMAKATO 16pcs Carburetor Jet Kit Main Jets for Mikuni VM22 VM24 VM26 125cc 150cc 200cc 250cc for Mini Bike Dirt Bike Pit Bike ATV 88 90 95 98 100 105 110 115 120 125 130 135 140 145 150 155 --- ## 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.in/products/318290599-rl-hm035a-ts002-digital-lcd-hours-tachometer-engine-temperature-gauge](https://www.desertcart.in/products/318290599-rl-hm035a-ts002-digital-lcd-hours-tachometer-engine-temperature-gauge) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-23*
