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."

To adjust breaker point opening, remove starting pulley, blower housing and flywheel from the engine

and

 

proceed as follows: (See Fig. 41.)

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.
