The Briggs & Stratton Raptor engine features a bore between 2.56125 and 2.5625 inches and a stroke of 2.438 inches. This corresponds to a total engine displacement of 12.48 cubic inches per engine cycle.
More modern Briggs & Stratton 5 horsepower engines feature the same 12.48 cubic inches of engine displacement, but achieve that volume of displacement using a wider bore and a shorter stroke. The currently produced Animal, 206 and World Formula engines feature a bore between 2.6875 and 2.6885 inches and a stroke of 2.2 inches.
The original Raptor series of engines featured a compression ratio -- the ratio of the length of the stroke to the length of the combustion chamber -- of 6.5 to 1. Despite their shorter strokes, modern Briggs & Stratton engines also feature shorter combustion chambers and thus have higher compression ratios. The World Formula has a compression ratio of 9.5 to 1, the 206 has a compression ratio of 9 to 1, and the Animal has a compression ratio of 8.5 to 1.
The factory-specified optimal ignition timing for the Raptor engine is 22 degrees before top of dead center (BTDC). The Animal, 206 and World Formula engines are factory-designed for an ignition timing of 29 degrees BTDC.
Many users modify their Briggs & Stratton racing engines to improve on, or the stretch the limits of, engine performance. If you purchase a used Briggs & Stratton motor, ask the seller about any modifications that have been performed and how they may affect engine performance.

Where are timing marks on 5HP Briggs and Stratton?
On a 5HP Briggs and Stratton engine, timing marks are typically found on the flywheel and the engine block. Look for a notch or a mark on the flywheel, which aligns with a corresponding mark on the engine block when the piston is at top dead center (TDC). These marks help ensure proper timing during assembly or maintenance. Always refer to the specific engine model's service manual for detailed guidance.
