For timing adjustment, the following proceduresusing a timing light: (SeeFig- 7-32)

Disconnect the stop button lead wires and the coil primary wire. Remove blower housing from engine.

Connect one of the timing light leads to the coil primary wire and ground the other lead to crankcase. (seeFig. 7-3-1)While the points are open, the light remains on and when the pointsare closed, the light is extinguished.

Turn flywheel slowly counter-clockwise (D type engines) or clockwise (B type engines) until the light extinguishes. Then, turn flywheelvery slowly clockwise (D type engines) or counter-clockwise (B type engines) and stop immediately the moment the lightlights up . Check if the slit on the flywheel is in the time with the mark on the crankcase. When the mark line is in alignment, the timing is correct.

If thetimingmark linesare not in alignment,thenre-adjustthepointopeningaccordingtothe BREAKER POINT ADJUSTMENT, by removing the flywheel and repeat the checking procedures3) through 5). Aftercompletingthetimingadjustment,re-mounttheblowerhousingandconnectthecoilprimaryleadtothestop button.
