MAXIMUM OUTPUT
The maximum output of the EC02-A and ECOZ-R is such standard power as developed by the engine, after its run-in period
with all the moving parts properly worn-in, when operating with the fully open throttle valve. Therefore, it follows that a new
engine may not develop this maximum output in the beginning, because moving parts are not
in
a properly worn-in condi-
tion.
