"This newer, OHV engine from Briggs and Stratton was designed to replace the old flathead, side-valve 10.5hp model. It does its job well. I have one of these, as well as a 9-hp version (basically the same engine) in use at this time. It starts easily with the electric starter, even when cold, and seems to run well. Power is adequate, if not as enduring (torque) as a flathead.
The only problem I have noticed with this engine is a tendency to kick back when starting with the recoil (manual) starter. You must be sure to bring the piston up to TDC on the compression stroke before letting the rope fly. Why? More compresson makes even a new engine want to spring back at times. It's a design issue that's more of an annoyance than a problem. Higher compression helps this engine to run more efficiently; the tradeoff being the starting issue as noted.
Overall, though, I enjoy using, and will continue to use, Briggs and Stratton engines on my equipment. It's hard to argue with my ol' reliable Briggs in use on another piece of equipment. It was set on fire (due to a fuel leak), overheated, has the intake valve seat peened in, has a scored cylinder, and knocks insistently. Yet, it fires right up every time. One puff of smoke, and off it goes. Ready to power through 2 ft of grass once more. I rest my case..."
