INITIAL STARTING ADJUSTMENTS
NOTE: For adjusting carburetor throttle linkage and
synchronizing carburetors, see section “Timing/
Synchronizing/Adjusting” of this manual.
After service or replacement of carburetor, turn low
speed mixture screw adjustment in (clockwise) until it
seats lightly, then back off (each carburetor) to speci-
fications (100-1-3/4 turns or 115-1-1/2 turns). This will
permit engine start-up.
LOW SPEED MIXTURE ADJUSTMENTS
NOTE: Only the top two carburetors on four cylinder
models have an adjustable low speed mixture screw.
1. Start engine and allow to warm up (run for several
minutes). Throttle back to idle for about one min-
ute to allow RPM to stabilize.
2. With engine running at idle speed (in water) in
“Forward” gear (prop on), turn low speed mixture
screw, IN (clockwise) until engine starts to “bog”
down and misfire. Back out 1/4 turn or more.
3. Check for too lean mixture on acceleration.
4. DO NOT adjust leaner than necessary to attain
reasonable smooth idling. When in doubt, stay on
the slightly rich side of the adjustment.
