(7) Turn the throttle valve adjusting screws
so the vacuum pressure of carbure-
tors #1, and #2 are within the specified
variations.
(8) Readjust the engine idling speed to the
specification.
(9) Rev the engine a few times and make
sure the vacuum pressures stay within
50 mm Hg (67 m bar, 1.97 in Hg) of each

EXAMPLE
If #3 valve is 300 mm Hg,
#2: #3 - 5 mm Hg =
300 - 5 = 295 mm Hg
#1: #3 - 10 mm Hg =
300 - 10 = 290 mm Hg
