Open the engine access door on the back side of the machine. Use the prop rod to hold the engine access door open.
The fuel system priming pump is located in the engine compartment on the front side of the engine.
Note: When the cam for the fuel pump is in the maximum lift position, the priming lever will not function. In this situation, the crankshaft must be turned one revolution.
- Push down on the top of the fuel priming pump plunger (1) and release the fuel priming pump plunger in order to operate the fuel priming pump. Operate the fuel priming pump plunger in order to fill the new filter element with fuel. Continue to pump until increased resistance is felt. This resistance will indicate that the filter element is full of fuel.
- Start the engine. If the engine does not start, further priming is necessary. If the engine starts but the engine continues to misfire, further priming is necessary. If the engine starts but the engine continues to emit smoke, further priming is necessary.
- If the engine starts but the engine runs rough, continue to run the engine at low idle. Continue to run the engine at low idle until the engine runs smoothly.
