Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.

noticeable loss of engine power:
:
Press down the interlock lever and
squeeze throttle trigger at the same
time, set the Master Control lever to
cold starter position l.
:

Wash the filter in a clean, non-
flammable solution (e.g. warm

Reinstall the air filter.
Motor Management
Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components (e.g.
carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.
