VERIFYING THAT THE PRIMER CONTROL IS CLOSED AND
LOCKED PRIOR TO ELECTRIC FUEL PUMP OPERATION.
This Service Bulletin applies to ali PA-28-160, -161, -180, -181 aircraft on
which STC SA2660CE has been installed.
It has come to our attention that an unlocked manual primer control may
allow fuel to be directed both to the carb and directly to the cylinders via
the priming system upon activation of the electric fuel pumps. This could
result in an a mixture that is too rich for proper engine operation, or could
increase the possibility of fire during engine-startup. Worn o-rings in the
primer could result in similar situations.
instructions:
Following normal engine priming make certain that the primer contro!
knob Is in the closed and locked position (pushed in and rotated till
locked) before activating a fuel pump or starting the engine. Check the
integrity of the primer o-rings at each annual or 100 hour inspection.
