Robin Subaru is moving in on what has been Honda territory for the past 20 years. This doesn't surprise us here for many reasons. The first and foremost reason is that Honda is still marketing a 25 years old design. The OHV (overhead valve) engine was a great step up from traditional small engines then, but now their design is tired, worn and outdated. And Honda, in their arrogance, doesn't care. Their engines normally work well and they have trained their customers well.
However, Subaru is marketing an OHC (overhead cam). This engine is more efficient and powerful for it's size. It is also lubricated better. Honda still depends on a "splash" system, which is really primitive. These Robins engines are actually CHEAPER than the same hp Honda.
What Is an Overhead Cam?
(OHC) A Camshaft Mounted above the Head to Activate the Valves is driven by a timing (cam) chain. Direct valve activation by a cam eliminates the need of pushrods and rocker arms, and their accompanying lash and inertia. Valves respond quicker, valve adjustment can be more accurate, and engine speed can be higher.
OHC Engines Offer Mechanical Advantages over Comparable Size Pushrod Engines:
• More power
• Higher engine speed
• Fewer moving valve train parts
• Greater precision
• Easier maintenance
Robin Subaru is One of the Four largest engine manufacturers in the World—
Subaru Robin currently produces over 1,200,000 engines annually. A line of engine models, ranging from 4 to 25 hp, is marketed direct to OEM accounts, plus a variety of other distributor, dealer, and retail outlets. Power equipment applications range through construction, industrial, agricultural, recreational, and rental markets.
All Robins engines are backed by Worldwide Fuji Network—
All products are backed by parent, Fuji Heavy Industries, Ltd. Group, Saitama, Japan. Subaru Robin offers a more comprehensive engine package than any other engine manufacturer. A two-year manufacturer’s warranty plus over 4,000 Robin parts & service dealers in the U.S. and Canada further strengthen appeal to the OEM. And Robin Subaru will actually honor the warranty, unlike Honda who has denied 99% of all warranties that we have submitted to them.
WagnerSprayTech has gone to the Robins engine exclusively. Graco and Airlessco are offering now offering other engines as options (instead of only Honda's). Most pressure washer companies offer other engines. We at Airless Spray Center think that this is a movement that is long overdue.
