MAINTENANCE
Removal of cooling passage blockages or cleaning of cooling fins is
considered "Normal Maintenance." Any failure attributed to lack of
maintenance is not warranted.
1. Remove spark plug lead.
2. Close choke (COLD START
[ ] position). This prevents
dirt from entering the
carburetor throat when the air
filter is removed. Remove air
cleaner cover (A).
3. Remove engine cover (B).
DO NOT use a metal scraper to remove dirt from the cylinder fins.
4. Use a brush to remove dirt from
the cylinder fins.
5. Remove ignition wires from clip
for cleaning.
6. Remove grass and leaves from
the grid between the recoil
starter and fuel tank.
7. Assemble components in
reverse order.
