I have 1998 25 HP Mercury that is flooding. Rebuilt carb, lowered float to the point it would not even run, Idle screw is all the way in. Raws gas comes out in the water. I purchased it used and it has been that way since I purchased. Checked compression 110# on top, 115# on the bottom. Runs good at WOT, 28 mph GPS on a 1448 jon boat. It has th e same symptoms as the You-Tube video with 8 parts. I appreciate any advise...
