Carburetor Adjustment
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.

1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above
