CARBURETOR ADJUSTMENT
WARNING!
Never start the engine without the complete clutch cover assembled!
Otherwise the clutch can come loose and cause injuries.
In the Carburetor, fuel is mixed with air. When the engine is tested at
the factory, the Carburetor is basically adjusted. Further adjustment
may be required from time to time, depending on climate and altitude.
The Carburetor has two possible adjustments:
1. Idle speed adjustment
(US Models
– only option available, EPA approved)
Due to EPA air quality regulations, on US models the Air/Fuel Mixture adjustment is pre-set on these carburetors
by the factory and can’t be adjusted by the consumer.
2. Air/Fuel Mixture adjustment
(NON US Models Only)
Idle Speed Adjustment
1. Start the engine.
2. Using a long, Philips head screwdriver
gently turn the top screw clockwise until the
XG-550 starts to move forward.
3.Then back out by turning the screw
counterclockwise until the XG-550 stops.
*Correct idle speed is obtained when the
engine runs smoothly just below the RPM
when the XG-550 starts to move.
Air/Fuel Mixture Adjustment
1. Start the engine.
2. Using a long, standard screwdriver and
while holding the throttle wide open, turn
the bottom screw (with spring) clockwise as
far as possible, then back out 1 & ¼ to 1 &
½ turns until the engine rums smoothly.
Note: Standard idle RPM is about
2500-3000RPM.
