high altitudeadjustmentisrequired.Operationwithoutthis adjustment
willcause decreasedperformance, i ncreasedfuel consumption, a nd
increased emissions.Seea Briggs& StrattonAuthorizedDealerfor
high altitudeadjustmentinformation.
Operationof theengineat altitudesbelow2,500feet (762meters)with
the highaltitude kit is not recommended.
HOW TO ADD FUEL
