* Replacement is recommended based on the finding of damage or wear
during inspection.
Carburetor Adjustment
Every unit is run at the factory and the carburetor is set in compliance with
Emission Regulations. In addition, the carburetor is equipped with “H” (High
Speed) and (“L” (Low Speed) needle adjustment limiters that prevent
settings outside acceptable limits.
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-in
period your engine performance will increase and exhaust emissions will
stabilize. Idle speed can be adjusted as required.
