"Installation/Timing. 1. Remove the points cover. 2. Remove the valve cover caps on the No 1 cylinder. 3. Turn engine to top dead center of No 1 cylinder with both valves closed. 4. Place transmission in 5th gear to keep engine from turning. 5. Remove point plate assembly, advance unit and stud. 6. Remove magneto outer drive cover and drive stud. 7. Remove O-ring from Honda point stud and install on magneto stud. 8. Install magneto stud in crankshaft and tighten with allen wrench inserted in predrilled hole. 9. Turn magneto so that line on large pulley lines up with line on magneto case. The magneto is now firing on the No 1 cylinder. 10. Recheck engine to ensure that TDC of No 1 cylinder is still retained. The pin hole in the crankshaft should be in line with Honda timing mark. 11. Install magneto on engine, ensuring that pin in magneto drive aligns with hole in crank. 12. Install 5 screws and tighten securely. 13. Install long center bolt and tighten. 14. The No 1 plug wire is marked and is located at 11 o'clock position as viewed from the left side of the engine. 15. Firing order is 1-2-4-3 counterclockwise rotation. 16. Timing is pre-set at 35 degrees. If a change is desired, loosen the center 7/16 in bolt. Loosen small allen set screws in drive pulley and rotate to desired timing position using a degree wheel to determine crankshaft position. 17. Retighten allen set screws (do not overtighten). This only holds pulley in place while timing magneto. Retighten large certer bolt. 18. Points should be set at 0.014-0.016 in. (0.36-0.40mm); plugs at 0.020 in. (0.51mm)."
