Ignition Components

Service of the ignition components is covered in Chap-
ter 5 – Electrical System.

Cooling System

IMPORTANT: The engine that powers the Flex 21 is
air–cooled. Operating the engine with dirty or
plugged cooling fins or a plugged or dirty blower
housing will result in engine overheating and dam-
age.
1. Park mower on a level surface. Make sure engine is
OFF. Remove high tension lead from the spark plug.
IMPORTANT: Never clean engine with pressurized
water. Water could enter and contaminate the fuel
system.
2. Clean cooling fins on cylinder and cylinder head. Re-
move engine shroud from cylinder for more thorough
cleaning (Fig.11).
3. Clean blower housing of dirt and debris. Remove
housing if necessary.
IMPORTANT: Never operate engine without the
blower housing installed. Overheating and engine
damage will result.
4. Make sure blower housing and/or engine cylinder
shroud are reinstalled to the engine if removed.
