STARTING THE ENGINE & RUNNING-IN ("Breaking-in")

For long life and high performance, every

engine needs to be 'run-in' or 'broken-in'. With

care, running-in of the MAX-21VZ-B V-Spec
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.

The following procedure is suitable for these

engines when the O.S. T-2050 tuned silencer

and a fuel containing up to 30% nitromethane
are used.
