Fuel Metering Systems Flashcards by Grace Margaret Alba When checking the idle mixture on a carburetor, the engine should be idling normally, then pull the mixture control toward the IDLE CUTOFF position A correct idling mixture will be indicated by a an immediate decrease in RPM b a decrease of 20 to 30 RPM before quitting c an increase of 10 to 50 RPM before decreasing A c 6
piston engine - Why does pulling the mixture to idle cutoff increase . . . Engine are usually run slightly richer than a stoichiometric mixture, to ensure reliable running and avoid overheating the pistons and valves When you cut off the fuel, it goes from slightly too much fuel to none - and so it's briefly at a stoichiometric ratio

Quiz FMS3 - Done (docx) - CliffsNotes Fuel flow meter 11 An indication that the optimum idle mixture has been obtained occurs when the mixture control is moved to IDLE CUTOFF and manifold pressure A Decreases momentarily and RPM drops slightly before the engine ceases to fire B Decreases and RPM increase momentarily before the engine ceases to fire C Increases momentarily and
Which manifold pressure indicates that the optimum idle mixture has . . . When the mixture control is set to IDLE CUTOFF, the optimum idle mixture is indicated by low manifold pressure This happens because reducing fuel intake decreases air pressure in the manifold Thus, low manifold pressure is a sign of an optimized idle mixture for smooth engine operation
