GASOLINE ENGINE CONTROLS
See Figure B.2 for the location of the following fea- tures:
1.FUEL SHUTOFF VALVE: Stops the flow of gaso- line from the fuel tank to the carburetor. Should be closed whenever you are finished using the
2.FUEL TANK AND CAP: Holds 1.0 gallon (3.8 liters) of unleaded gasoline. Contains a 50 micron fuel filter molded at the outlet port.
NOTE: If you use any other alternate fuel tank or supply, be sure to use a recommended in- line fuel filter.
3.MUFFLER: Reduces engine noise output. Does not serve as a spark arrester. See SPARK ARRESTER in the INSTALLATION section of this manual.
4.ROTARY STOP SWITCH: Stops the engine by grounding the ignition circuit.
5.AIR CLEANER: Filters intake air to the carburetor. See ENGINE MAINTENANCE in the MAINTE- NANCE section of this manual for details about the specific type of air cleaner to use.
6.CHOKE: Provides a richer air/fuel mixture for cold engine starting con- ditions. See the topic ENGINE OPERATION, below, for details on setting the choke.
