5-5 BREAK-IN OPERATION
An engine that has been completely overhauled by being fitted with a new piston, rings, valves and
connecting rod should be thoroughly RUN-IN before being put back into service.
Good bearing surfaces and running clearances between the various parts can only be established by
operating the engine under reduced speed and loads for a short period of time.
While the engine is being tested, check for oil leaks.
Make final carburetor adjustment and regulate the engine operating speed.
6. MAGNETO
6-1 FLYWHEEL MAGNETO
The ignition system of the EH36/EH41 is a pointless flywheel magneto with automatic advancing char-
acteristic.
Being different from the breaker point type ignition system, this system is completely free from such
troubles as starting-up failure due to dirty, burnt or corroded point surface.
The electronic automatic advancing ensures extremely easy starts and stable high performance at oper-
ating speed by advancing the ignition timing to the most suitable point.
6-2 BASIC THEORY
(1) Revolution of the flywheel generates electricity on the primary side of the ignition coil, and the base
current I
1 flows to the power transistor.
Current I
1 turns the power transistor “ON” and the electric current I2 flows.
