High Altitude Engine Operation

•Please have an authorized Robin America service dealer modify this engine if it is to be run continuously above 5,000 feet (1,500 meters). Failure to do so, may result in poor engine performance, spark plug fouling, hard starting, and increased emissions.

•Carburetor modification by an authorized Robin America service dealer will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emission standards throughout its useful life.

•An engine converted for high altitudes can not be run at 5,000 feet or lower. In doing so, the engine will overheat and cause serious engine damage. Please have an authorized Robin America service dealer restore high altitude modified engines to the original factory specification before operating below 5,000 feet.

Spark Arrestor (Optional)

In a dry or wooded area, it is recommendable to use the engine with a spark arrestor. Some areas require the use of a spark arrestor. Please check your local laws and regulations before operating your engine.

The spark arrestor must be cleaned regularly to keep it functioning as designed.

A clogged spark arrestor:

•Prevents the flow of exhaust gas

•Reduces engine output

•Increases fuel consumption

•Makes starting difficult

If the engine has been running, the muffler and the spark arrestor will be very hot. Allow the muffler to cool before cleaning the spark arres- tor.

How to remove the spark arrestor

1.Remove the flange bolts from the muffler cover and remove the muffler cover.

2.Remove the special screw from the spark arrestor and remove the spark arrestor from the muffler.

Clean the spark arrestor screen

Use a brush to remove carbon deposits from the spark arrestor screen. Be careful to avoid damaging the screen.

The spark arrestor must be free of breaks and holes. Replace the spark arrestor if it is damaged.

Install the spark arrestor, and muffler protector in the reverse order of disassembly.
