Carburetor Adjustment
The blades must not move at idle, otherwise serious personal
injury may result. Periodic carburetor adjustment may be
necessary to assure blades do not move at idle.
If blades move, readjust carburetor according to these
instructions, or see your dealer.
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.
