In the manual it gives fuel burn in lbs per hour. Are those values for both engines combined? Does a burn of 430lbs/hr in manual and the 430lbs/hr on the instruments the same, or should I double the actual burn rate since there are two engines...thus run each engine at 215lbs/hr?Does the mixture knobs affect fuel flow or are they just basically fuel on/fuel off? It seems leaning the mixture levers has no visible affect on fuel burn per hour, nor am I noticing a change in temp on the EGT dials(those are the top two right?).Help me please!Charles Wilson
