How much did you have to drop? My sweet spot was 3.25-3.5 on my Bobs gauge and after putting in 3 Liths I had to drop a whole number. I first ran it on 3.25 like usual and the motor was way to high...Just curious if anyone else had to drop it that much. Ran it on 2.5 and it was about like it used to be with 40 gals of fuel in it.
