3. Start the engine and run at half throttle for 5 to 10
4
minutes to warm up. The engine must be warm
before making final settings.
Main Fuel Needle Setting: This adjustment
is
required for adjustable
main jet carburetors
only.
If the carburetor
is a fixed main jet type refer to
Walbro adjustment.
Place the throttle into the wide-open
or "fast"
position. If possible, place the engine under load.
Turn the main fuel adjusting
needle out
(counterclockwise)
from the preliminary
setting
until the engine speed decreases
(rich). Note the
position of the needle.
Now turn the adjusting
needle in (clockwise).
The
engine speed may increase, then it will decrease
as the needle is turned in (lean). Note the position
of the needle.
Set the adjusting needle midway between the
rich and lean settings.
5. Low Idle Speed Setting: Place the throttle
control into the "idle" or "slow" position. Set the
low idle speed to 1200 RPM* (+ 75 RPM) by
turning the low idle speed adjusting screw in or
out. Check the speed using a tachometer.
*NOTE: The actual low idle speed depends on
the application
- refer to equipment
manufacturer's
recommendations.
The
recommended
low idle speed for basic
engines is 1200 RPM. To ensure best
results when setting the low idle fuel
needle, the low idle speed must not
exceed 1500 RPM.
6. Low Idle Fuel Needle Setting:
Place the throttle
into the "idle" or "slow" position.
Turn the idle fuel adjusting
needle out
(counterclockwise)
from the preliminary
setting
until the engine speed decreases

position of the needle.
Now turn the adjusting needle in (clockwise).
The
engine speed may increase, then it will decrease
