2 notches for every 1000 meter change
in altitude,
: Open the throttle wide.
At high altitudes
: Turn the high speed screw (H)
clockwise (leaner) no further than
stop until there is no noticeable
increase in engine speed.
At sea level
: Turn the high speed screw (H)
counterclockwise (richer) no further
than stop until there is no noticeable
increase in engine speed.

speed may be reached with the
standard setting in each case.

It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
