GASOLINE ENGINE CONTROLS

Refer to your engine manual for the location of the following features:

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 BULLDOG™ 140. Must be opened before you start the engine.

2.FUEL TANK AND CAP: See TECHNICAL SPECI- FICATIONS for capacity.

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.

See SPARK ARRESTER in the INSTALLATION section of this manual.

4.“ON/OFF Switch: A two position switch located on the rear of the engine. In the “ON”(I) position, the engine ignition circuit is energized and the engine can be started by pulling the recoil rope starter. In the “OFF”(O) position, the electronic ignition is grounded and the engine shuts down.

5.AIR CLEANER: Filters intake air to the carburetor. See ENGINE MAINTENANCE in the MAINTE- NANCE section of the engine owner’s manual for details about the specific type of air cleaner to use.

6. CHOKE: Provides a richer air/fuel mix- ture for cold engine starting condi- tions. See the topic ENGINE OPERA- TION, below, for details on setting the choke.

7.RECOIL STARTER: Manual, rope-type starter. The handle position allows easy starting from either ground level or pickup-truck level

8.OIL DRAIN PLUG: Permits convenient draining of engine oil during maintenance. Both sides of the engine are equipped with an oil drain plug.
