8. CHECKING BOLTS, NUTS AND SCREWS
• Retighten loose bolts and nuts
• Check for fuel and oil leaks
• Replace damaged parts with new ones.
9. HIGH ALTITUDE ENGINE OPERATION
• Please have an authorized Subaru Robin service dealer modify this engine if it is to be run continuously above 5000 feet
(1500 meters). Failure to do so, may result in poor engine performance, spark plug fouling, hard starting, and increased
emissions.
• Carburetor modification by an authorized Subaru Robin service dealer will improve performance and allow that this
engine meets EPA (Environmental Protection Agency) and CARB (California Air Resources Board) emission standards
throughout its useful life.
• An engine converted for high altitudes can not be run at 5000 feet or lower. In doing so, the engine will overheat and
cause serious engine damage.
Please have an authorized Subaru Robin service dealer restore high altitude modified engines to the original factory
specification before operating below 5000 feet.
