6.	MAGNETO
6-1 MAGNETO
The spark for ignition is furnished by a magneto assembly. The magneto consists of a flywheel, ignition coil					/
and contact breaker assembly (including condenser), of which flywheel is mounted on crankshaft and igni-
tion coil contact breaker are mounted in crankcase directly. The EY20V type engine normally incorporates a
solid state ignition system(T.I.C.) described in 6.5 "SOLID STATE IGNITION."
6 -2 BREAKERPOINTADJUSTMENT (Fig.41)
The breaker points, which are mountedin the crank-
case inside the flywheelshould be checkedtwicea
season or whenever the ignition spark becomes weak.

To adjust breaker point opening, remove starting pulley, blower housing and flywheel from the engine				and
proceed as follows: (See Fig. 41.)
the	Remove				,

Turn the crankshaft over until the breaker arm comes in contact with thehigh point of the breaker cam. (Maximum point opening: 0.35 mm)

Loosen the contact support plate lock screw just enoughso that breaker can be moved. Insert a 0.35 mm feeler gauge between the points.

Caution: Adjust the breaker point gap without opening it more than 2 mm, otherwise rated heel-pressing force may not be obtained due to the bending of contact breaker arm.

Apply a screw driver t o adjust tab and move the contact support plate just enoughso that a slight drag is felt while sliding the feeler gauge from the gap between the points.

Tighten the lockscrew- and recheck the breaker pointgap.

Pull a stripof 8 10 mmwide whitepaperthroughthe closed pointsto removeoilandduston the point surfaces.

Caution: When inserting a sheet of paper, never open the breaker point gap more than 2 mm.

Mount the flywheel, blower housing and starting pulley on the engine after adjustment.
