4-11 COOLING DEVICE
The cooling fan serving also as flywheel cools the cylinder and cylinder head by forced air cooling. An air guide plate and
head cover are used to let the cooling air go through.
The cooling fan employs curved blades so Types B and D have cooling fan parts special to their own.
4-12 LUBRICATION
". .
The rotating and sliding parts are being lubricated by scooping
and splashing the oil in the crankcase with the oil scraper
attached to the connecting rod.

4-13 IGNITION DEVICE
Models EY35 and EY40 have a flywheel magneto type ignition system (Fig. 13) with an ignition timing of 23" before TDC
(Top Dead Center). The flywheel (also serving as fan) is fitted onto the crankshaft; and the
ignition coil, contact breaker,
and charging coil are directly assembled with the crankcase. An S.S.I. electronic system (Fig. 14) is also available in types,
including a 1 SO-watt load type.
The S.S.I. system, except the 150-watt type, electrically advances the ignition timing. The ignition timing after this advance
is 23" before TDC. (See Figs. 13 and 14.)
