How do you set ignition timing on a 14.5 ohv Briggs?

To set the ignition timing on a 14.5 OHV Briggs & Stratton engine, first, remove the flywheel shroud and locate the timing key on the flywheel. Use a dial indicator to find top dead center (TDC) on the piston, then align the timing mark on the flywheel with the mark on the engine block. Adjust the position of the ignition coil if necessary, maintaining a gap of about 0.010 inches between the coil and the flywheel. Finally, reassemble all components and test the engine to ensure proper operation.
