I have flown many Cessna 206s and 207s with either IO520F or TSIO520M and on all of them the fuel selector has 3 positions, Left, Right and Off. It does not have both and Off is between Left and Right so one has to pass through Off whenever one changes tanks. The engine never quits doing that. In fact you can pause for a second or two without it missing. There must be enough fuel in the fuel pump or lines to keep it running for a bit. Dan Rogers Gary Casey wrote: > >Here I disagree.
