acquired a center console with an older DT85 (white) and have good, solid compression on all 3 cylinders (less than 4lb variation) and good strong spark. It runs like a champ with the flush boot on. Put her in the water and it won't get out of her own way . Upon further digging, it appears to be the bottom cylinder and it just wont run on it. I am NO marine tech by any means, but have built my share of muscle cars so I rebuilt the bottom carb and still the same thing. Any suggestions or recommendation as to my next step would be greatly appreciated. Repo
