Small Gas Engines
The Briggs & Stratton Raptor series is a line of single-cylinder, four-cycle flathead engines that has been in use since the early 1970s.
Released in 1995, the third and final Raptor, the Raptor III, had five horsepower. The only thing different from the II was that this one had a cast-alloy crank with a carbon-infused piston. This engine sold phenomenally, however, and almost phased out its two predecessors. Hundreds of thousands of these engines remain in service today, and are the best-selling racing engine of all time.
