I have a Shadin Miniflow fuel totalizer in my aircraft.  It has always been steady (around 7.5 gph) cruising low with my O-320.  Last flight I noticed it was reading a little high, and would sometimes scroll up to around 9gph, then stabilize again...the so on and so on.  Does this sound like a problem with my totalizer or my aircraft (engine, carb?).  Thanks.
