The important thing to do in a run-in is to heat-cycle. Therefore one
of the most important points is to observe the temperature of the
engine. Runing in an engine should not, as Glen has stated, be done
by idiling the engine - this doesn't allow the engine to reach the
optimum operating temperature.
Make sure you set your engine on the rich side and run the engine in
the first couple of tanks no more than half throttle - use the HSN to
maintain the temp @ 95-105 Degrees C or 200-220 Degrees F. Some say
to run the eingine at WOT even at this stage, but my personal
preference is to let the components bed-in and not stress them too
heavily for the first couple of tanks. After the first couple of
tanks then increase the throttle, but maintain the temp as above.
Other people have other break-in methods using WOT and higher temps -
it is basically personal preference. The one which really doesn't
work is letting the engine idle through a few tanks.
Cheers, Mark.
