Replacing the Air Filter

If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a soiled air filter, the spark plugs can obtain a coating that disrupts operation.

For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).

2.Remove the foam rubber pre-filter and clean using a mild detergent.
