You have an 8 hp Briggs and stratton cam with no marks for timing how do you determine correct tooth mark location?

To determine the correct timing tooth mark location on an 8 hp Briggs and Stratton cam without existing timing marks, you can align the piston to top dead center (TDC) on the compression stroke. Then, position the cam gear so that the cam lobes are pointing away from the follower, ensuring that the timing gear's position aligns with the crankshaft. Once this is achieved, you can create your own timing marks on both the cam and crank gears for future reference. It's essential to double-check that the engine runs smoothly after installation.
