For long life and high performance, every
engine needs to be 'run-in' or 'broken-in'. With
care, running-in of the MAX-21TM can be
carried out with the engine installed in the
vehicle. Be sure to install the air-cleaner on the
carburetor and use a muffler-pressurized fuel
system.
STARTING THE ENGINE & RUNNING-IN ('Breaking-in')
Fill the tank completely with fuel.
The somewhat violent changes of vehicle
attitude that occur in off-road running,
combined with the fact that, in buggy type
cars, the fuel tank is often located some
distance from the carburetor, means that fuel
'head' at the carburetor can vary and upset
running.Therefore,it is recommended that a
muffler pressurized fuel feed system be used.
Never run your vehicle without installing the
air cleaner. Dust and dirt that may otherwise
be drawn into the engine will rapidly shorten
its life.
Temporarily remove the glowplug to check
that it glows bright red when energized.
