CAUTION:
If a change in conditions require a main jet
of a larger size, use the size to which #20 is
added for safety.
NOTE:
• Since this correction coefficient table lacks a
column for humidity, it is advisable to check
the degree of discoloration of the spark
plug(s) for final selection according to an
explanation under "Atmospheric conditions
and carburetor setting'' (P7-1).
• As the main nozzle is more susceptible to
other than atmospheric conditions, no correc-
tion coefficient is used for main nozzle set-
ting.
