Starter WARNING! • The recoil spring sits in its tensioned posi- tion in the starter housing and can with careless handling fly out and cause personal injury. • When replacing the recoil spring or the starter cord great care should be exercised. Always wear protective glasses.
Spark plug The condition of the spark plug is affected by: • An incorrect carburettor setting. • An incorrect fuel mixture (too much oil). • A dirty air filter. These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.
