WEBER 4 BARREL CARBURETOR - 5D-13
FINAL IDLE SPEED AND MIXTURE
IMPORTANT: Boat MUST BE in the water and en-
gine at normal operating temperature to accu-
rately check and adjust idle speed and mixture.
Carburetor should be set so that engine idles as
smoothly as possible, with boat in the water, engine
normal operating temperature and drive unit in for-
ward gear. To adjust idle speed and mixture, proceed
as follows:
IMPORTANT: DO NOT attempt to compensate for
other engine problems (incorrect ignition timing,
faulty ignition components, low compression,
vacuum leaks, etc.) with carburetor adjustments.
This will only cover the problem, which must be
corrected if engine is to achieve maximum fuel
economy and performance.
1. Connect a shop tachometer to engine.
IMPORTANT: DO NOT turn idle mixture screws
(needles) tightly into seat, as damage to needle
and/or seat may result.
2. If a new or rebuilt carburetor has been installed,
turn each idle mixture screw until it LIGHTLY con-
tacts seat (if not already accomplished), then
back out 1-1/4 turns. This will provide a sufficient
setting to allow starting the engine.
3. Start engine and run at 1500 RPM until engine
reaches normal operating temperature.
!
WARNING
DO NOT leave helm unattended while performing
idle speed and mixture adjustments, following.
BE CAREFUL NOT TO ACCIDENTALLY
ACCELERATE ENGINE WHILE PERFORMING
ADJUSTMENTS.
4. With boat in open water, place remote control in
forward gear, idle position.
5. Disconnect throttle cable barrel from anchor
stud. BE SURE NOT TO LOSE SPACER ON AN-
CHOR STUD.
6. Adjust idle speed adjustment screw to obtain
specified idle RPM. (Refer to Section 1B -
“Tune-Up Specifications” charts.)
NOTE: Idle speed must be at specified RPM or less.
Or engine will be operating on the off idle circuit. Mix-
ture screw adjustments will be ineffective if this
condition exists.
7. With engine running at or just below specified idle
RPM, adjust idle mixture screws as follows:
a. Turn idle mixture needle in (clockwise) until
the engine speed begins to decrease due to
LEAN mixture.
b. Turn same idle mixture screw outward (coun-
terclockwise) until the engine speed begins to
decrease due to a RICH mixture.
c. Turn screw in to a point between these two
extremes to obtain maximum engine smooth-
ness and RPM.
d. Repeat procedure with other mixture screw.
e. Readjust idle speed adjusting screw, if nec-
essary, to obtain specified idle RPM.
8. Place remote control in neutral. Turn ignition
OFF.
9. Accelerator pump linkage should be rechecked
at this time. Refer to Steps 3 and 4, of Adjust-
ments – “Accelerator Pump”, as previously out-
lined and verify pump is set at 7/16 in. (11mm) as
specified.
10. Refer to SECTION 2. Install and adjust throttle
cable following instructions appropriate to your
power package.
