CARBURETOR ADJUSTMENTS
Carburetor adjustment is critical and if done
improperly can permanently damage your
unit We recommend you contact an Autho­
rized Service Dealer for adjustments.
IDLE SPEED ADJUSTMENT. Turn the Idle
Speed Screw clockwise until it stops. Now
turn the screw counterclockwise 4-1/2
turns. This should allow the engine to run
without the chain turning. If the chain
moves at idle speed, do not use your unit
Contact an Authorized Service Dealer. Idle
speed is correct when engine runs without
stalling and chain does not turn.
MDG^RE ADJUSTMENTS: Your Carbure­
tor includes limiter caps (Plastic caps on the
mixture screws) , do not force the screws
beyond the stops of the limiter caps or dam­
age will occur. Do not remove these caps.
Small adjustments will affect your unit Do
not adjust more than 1/16th turn without
checking performance.
