3 Operate the fuel lift pump priming lever X slowly, for
approximately two minutes. The engine is now ready to
start. If the engine runs smoothly for a short time, and
then begins to run roughly or stops, check again for air
in the fuel system. Check all seals and connections,
especially in the low pressure side of the system.
Note: If no fuel is moved when the fuel lift pump priming
lever X is operated, then the pump diaphragm may have
rested in a 'maximum lift' position. To move the diaphragm,
use the starter key to turn the engine, then try the priming
lever again.
