SLOW SPEED MIXTURE ADJUSTMENT
1 Remove access plug from cover.
2 Before starting engine, turn the slow speed mixture screw in until it is lightly
seated then back it out 1-1/2 turns.
3 With the boat tied securely to dock, start engine and allow it to warm up.
4 Shift the outboard to forward gear and reduce engine speed to idle.
5 Turn the slow speed mixture screw slowly in until the engine starts to misfire or
stall due to a lean mixture. Note the position of the screw slot.
6 Turn the slow speed mixture screw slowly out until the engine starts to “load up”
or fire unevenly due to a rich mixture.
7 Set the slow speed mixture screw midway between the rich and lean setting.
When in doubt, set the mixture slightly rich rather than too lean.
