Running rich

"Any fuel entering a flame will be reacted.": I thought if an engine is "running rich" (see Carburetor#Carburetor adjustment) there is more fuel stoichiometrically speaking than air, so there will be fuel "enternig the flame" that can't be burnt because there's no oxygene to oxidize it.--ospalh (talk) 12:20, 9 July 2010 (UTC)[reply]
