8.21 FUEL SYSTEM
(a) Servicing Fuel System
At every 50 hour inspection, the fuel screens in the strainer
and in the carburetor must be cleaned. The screen in the carburetor
is located in the housing where the fuel line connects to the
carburetor. The fuel strainer is located on the lower left side of
the firewall and is accessible for cleaning with the lower cowl
removed. After cleaning, a small amount of grease applied to the
gasket will facilitate reassembly.
(b) Fuel Requirements (AVGAS ONLY)
The minimum aviation grade fuel is 100. Since the use of lower
grades can cause serious engine damage in a short period of time,
the engine warranty is invalidated by the use of lower octanes.
