That's a very different engine than the flat-heads. Most likely a Chinese import.
This is the first year I've noticed this Briggs labeled, 140cc OHV engine on units sold at my local home/hardware stores.
I assume it will eventually phase out the flat-heads all together.
Like I always say, I like the smoothness, power and low fuel consumption of these OHV engines, but are they as simple and long lasting as the old flat-heads? Probably not.
