I have a 1997 40 hp evinrude two stroke motor. When trying to start gas comes out of the foot and will not crank.After sitting over night it cranks right up.After cranking it runs fine and will crank right up until it sits for a few days and then it will flood out again. It has been doing this for about a month. So I rebuilt both carbs thinking that the float needle may have been sticking.I also just put a new fuel pump on doing away with the vro pump.Any ideas?
