Honda really changed the small engine market design with their engines. They made a great, if expensive, gas mower. This coming from a man who grew up with a father who was a traveling salesman selling lawn and garden equipment to independent dealers in several states, mostly Lawn Boy and Ariens IIRC. My mechanic life started as a small engine mech and I have seen and maintained/repaired MANY a Lawn Boy, Briggs & Stratton, and Tecumseh motor. The Honda design finally drug the small engine market out of the 20s and into the 50s+ (Flat-heads to OHV).
