695GC/F4 SERVICE MANUAL

TROUBLESHOOTING

24.4

Test the main fuel pick-up for leaks.

Install the pressure gauge and bulb to

the filter end of the fuel line.

Pressurize the tube to 7psi (0.5 bar)

If the pressure does not maintain,

separate the fuel line from the carburetor

24.6

The fuel tank breather stabilizes the

pressure in the fuel tank preventing both

excessive pressure, which could flood

the engine and negative pressure which

could starve the engine of fuel.

24.5

Plug one end of the fuel pick-up tube.

Pressurize the tube to 7 psi (0.5 bar).

If the pressure holds, the leak has been

isolated to the carburetor. Refer to the

Walbro Carburetor Service Manual.
