Shryp. Come to think of it even the Tecumseh would use more gasoline to blow my driveway than does the new OHV Predator 212cc. Since the Predator is 212cc and 7hp so 7hp/212cc =0.033Hp per cc so the Big Flat head 8hp Briggs is 319cc and if it made as much power per cc as the 212cc engine it would have to put out 10.533hp. The OHV engines are much more efficient than the old Flat heads and subsequently much more fuel efficient. I am glad that you agree with me that a modern OHV engine with Ball bearing crankshaft support is technologically superior to an old valve in block fat head with crank shaft bushings instead of bearings. I was reluctant to try and use the Flat head Briggs because of my prior experience with my Tecumseh flathead.
