Subaru, as in the company that builds cars, namely the Forester, Impreza, and others, also has a range of multi-purpose engines used in Lawn Mowers.
Or, rather they used to before selling their small engine power products business to Yamaha in 2017. Subaru expressed that they wanted to focus their efforts on the car industry. (cited from https://subarupower.com/).
I’m sure most will agree they are an exceptional engineering company.
Even though Subaru Lawn Mower Engines production has ceased, you can still find a few models around. Such as the Ryobi RLM46175S Subaru Engine Lawnmower with Cutting Width 46 cm, 175... or in the US, then Walmart has Powerstroke, although who knows how long these will last!
Worried About Your Existing Sabaru Engine Breaking Down?
If you currently own a Subaru Engine Powered lawnmower, don’t worry about maintenance. The parts to maintain the engines are still in production and freely available online and at your local retailers.
EA Series Engines
Subaru was the first manufacturer to offer chain-driven overhead cams in small, air-cooled vertical shaft engines. Lightweight yet powerful enough to be used with equipment like lawnmowers, pressure washers, walk behind string trimmers, posthole diggers, and lawn vacuums.

Troubleshooting: Subaru Engine Hard To Start.
1. Check Spark Plug
Make sure that the spark plug is not damaged or worn. Replace the spark plug if the porcelain insulator is cracked, an electrode is damaged or burned away, or there are heavy carbon deposits at the electrode.
The engine can receive too much or too little fuel. A faulty carburetor usually causes this. Clogged carburetors will not provide enough fuel for an engine. When the carburetor choke doesn’t close correctly, too much fuel may flow into the engine. UK Link.
3. Fuel Cap
Fuel consumption increases the gas tank’s pressure. A small vent on the gas cap allows air into the tank to relieve this pressure. Clogged gas cap vents prevent air from entering gas tanks, which leads to a rise in pressure. Often, the engine will not start when the gas tank pressure exceeds the engine’s pressure. If you are experiencing a clogged gas cap vent, try loosening it slightly and starting the engine—time to replace the gas cap.
