Subaru Engines
High Performance
What’s the benefit of Subaru’s advanced mechanical decompression system?
Easy Starting
With 30 to 40 percent less recoil pulling force than competitive
models, Subaru engines provide smooth, easy starts. Sure,
all engines start easily when they’re brand new. Subaru OHC
engines continue to start easily even after thousands of hours
of use.

Max Power
Overhead cam (OHC) technology and the hemispherical combustion chamber allow the Subaru EX
engines to use a higher compression ratio up to 9:1.
What is the significance of a higher combustion ratio?
More Power
A more powerful engine makes for more powerful and productive equipment.
Increased Efficiency
Lower fuel consumption and efficient performance reduce operating costs.
