Steps for Replacing and Cleaning Air Filter
(Block Style Foam Filter)
1. Before removing the air filter cover, move the choke lever to
the CHOKE position.
2. To remove air filter cover, squeeze the latch tabs on both sides
of the cover. SEE FIGURE 8
3. Once the latch tabs are released, remove the air filter cover
by rotating the cover away from the engine.
4. Remove the foam filter element (SEE FIGURE 8). Replace with
a new oiled foam filter or clean the original foam filter with
warm water and mild soap. Remember to thoroughly oil the
foam filter with 30 or 40 weight motor oil and squeeze out any
excess oil before reinstalling it. Make sure to press the foam
filter evenly into place over the filter reinforcement plate to
ensure that the foam is fully seated into its sealed position.
5. Replace the air filter cover so that it fully snaps into place and
is secured by the latch tabs. Check that the cover is securely
attached by pulling slightly on the cover. If the cover doesn’t
move when pulled, it is secure.
