Replace worn parts as necessary. Pumping the footfeed during this time simply prolongs the agony, as the accelerator pump will pump the fuel into the engine, but in amounts insufficient for starting. Fuel delivery system test - basically, you are checking to make certain the fuel delivery system is delivering fuel to the carburetor. This reduces fuel flow by closing the passageway through the rich jet. Roll the new ring on over the holder.

- It is important to start the engine prior to doing this test.
- Note that on the diaphragm edge there is a tab that fits into a slot in its seating on the chamber base.
The inverse is also true when the aircraft is in inverted flight. The pressure will force the liquid from the float.
