To set the timing on a 12.5 hp Briggs & Stratton engine, first ensure the piston is at top dead center (TDC) on the compression stroke. Remove the flywheel cover and locate the timing key or mark on the flywheel and the engine case. Align the timing mark on the flywheel with the timing mark on the engine, ensuring the key is not damaged. If necessary, adjust the position of the ignition coil to ensure the spark plug fires at the correct timing, typically just before TDC.

To set the timing on a 16.5 hp Briggs & Stratton engine, first, remove the flywheel cover and locate the timing mark on the flywheel and the engine block. Rotate the flywheel until the timing mark aligns with the pointer on the engine. Next, check the ignition module's position; it should be set according to the manufacturer's specifications, usually with a specific gap between the module and the flywheel. Finally, secure everything back in place and reassemble the engine components.
Both marks must FACE each other and cannot be off by even one tooth.
To set the timing on a Briggs & Stratton 19.5 hp lawn tractor engine, first ensure the engine is off and cool. Remove the crankcase cover and locate the timing marks on the flywheel and the engine block. Align the timing marks to the specified position, typically at TDC (top dead center) for the compression stroke. Finally, reassemble any removed parts and check the timing by starting the engine and listening for smooth operation.
Yes, you just aline the divot on the Cam gear with the dash on the Crank gear. Very easy to do.

Timing on all Briggs & Stratton small engines is set at the factory and non-adjustable. It is determined by the placement of the armature (coil) and position of flywheel on crankshaft. Unless the crankshaft is bent or the flywheel key is sheared (both are possible after an impact or sudden stoppage), timing is perfect. Rough running is likely an intake or mechanical problem.
the timing is non adjustable, if the key looks offset it is bent and needs replacing
open up the crank case then you will see 2 marks one on the camshaft and one on the crankshaft mach thoes two up then close the crankcase back up .
timeing is controled by a key way under the flywheel, if its off te keyway is bent, there is also timing marks on the crankshaft and cam gears. these need to be lined up on top dead center. be careful as not to set them 180 degrees off or the engine will backfire.
