These engines started out as Wisconsin engines. Through acquisitions become Robin-Wisconsin then just Robin. Through the acquisition by Subaru they became Robin-Subaru now they are just Subaru. The older engines were well made engines but I don't about the latest engines as they haven't made into my shop yet.
In my area it is the Kohler, Kawasaki, and Briggs that are the most common mower engines. The Subaru engine and all the previous names they were once was have been fairly problem free other carburetor problems here.
