Ignition Timing
To check the spark timing when necessary, proceed as follows: Fully
advance spark by moving spark lever (left lever at top of steering wheel)
down to lowest position, or nearest driver.
Take out the spark plug in No.1 cylinder and crank the motor by hand
until the rush of air from the plug opening indicates that the piston is coming
up on compression stroke. This can readily be determined by placing a finger
over the spark plug opening. The motor should then be cranked very slowly
until the pointer on the observation hole (on the left side of the flywheel case)
is directly over the center of the mark "A," which is stamped on the flywheel.
It is permissible to time slightly ahead of this point if found necessary.
Results should be checked on road and spark retarded slightly if there is any
tendency to knock.
Remove the distributor cap and rotor, and note position of contact points.
If they are set to proper clearance (as shown below), they should be just
separating. To adjust, if necessary, loosen the holding screw on the distribu-
tor timer arm shown in the illustration on page 7 and turn distributor housing
slightly in proper direction.
Turn the distributor to the left, or anti-clockwise, to advance the ignition;
to the right, or clockwise, to retard. Then re-tighten the holding screw.
The motor fires in the following order: 1~5~3~6~2~4.
The ignition distributor requires no attention
other than that pointed out in the illustration.
