Using a PDF-printed degree disc transforms an intimidating task into a methodical, accessible process. After printing the disc on heavy paper (to resist tearing and moisture from engine oil), the user cuts out the circle and punches the center hole. The disc is then slid onto the crankshaft. To ensure accurate timing, the mechanic first finds true TDC (Top Dead Center) using a piston stop tool or a dial gauge through the spark plug hole. The degree disc is rotated until the TDC mark aligns with a fixed pointer—often a piece of stiff wire screwed into a nearby stator plate hole. Once zeroed, the flywheel is turned counterclockwise (direction of engine rotation) to the specified advance angle. The stator plate is then adjusted so that the points just begin to open (or the electronic trigger aligns with the flywheel’s pickup) at that exact degree mark. This guide provides a basic approach
