These engines are equipped with a replaceable, high
density paper air cleaner element and most also have
the optional oiled, foam precleaner which surrounds
the paper element.
Two basic types of air cleaners are used. The original
confi guration is shown in Figure 4-1 and the later
confi guration in Figure 4-2. On the original style, air
is drawn through a duct from the blower housing and
from the outside slot. The later type uses a fl at base
plate with the enclosure provided by the cover.
