That's
normal Les. The cowl flapper/door runs off engine vacuum. When the
engine is running the vacuum holds it shut. When you stomp on the gas the
vacuum drops causing the door to open, the same thing happens when you shut off
the engine - no vacuum.

-----Original Message-----THE COWL INDUCTION FLAPPER ON MY 1970 396/350 POPS UP AND REMAINS UP WHEN ENGINE IS SHUT OFF. WHEN ENGINE IS STARTED IT SHUTS AND FUNCTIONS CORRECTLY. ANY SUGGESTIONS AS TO THE PROBLEM? THANKS, LES.
