Briggs & Stratton 1900 PSI - Manuel (Page 9)

To protect the fuel system from gum formation, mix in a fuel
stabilizer when adding fuel. See Storage. All fuel is not the
same. If you experience starting or performance problems
after using fuel, switch to a different fuel provider or change
brands. This engine is certified to operate on gasoline. The
emission control system for this engine is EM (Engine
Modifications). 1. Clean area around fuel fill cap, remove cap.
2. Slowly add regular unleaded fuel (A) to fuel tank (B).
Becareful not to overfill. Allow about 1.5" (4 cm) (C) of
tank space for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate before
starting engine.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See an Authorized Briggs & Stratton
dealer for high altitude adjustment information. Operation of
the engine at altitudes below 2,500 feet (762 meters) with
the high altitude kit is not recommended.
