I have a 1991 25hp. I am seeing a lot of oil residue coming out of the bottom of the cowling. Not sure if my float is sticking or what. Motor runs just fine. Worried about potential problems.
Pump the fuel bulb up and look for leaks around the lines and carbs.If it was a needle and seat stuck open then the bulb would not pump up firm.
I had the same problem and it ended up being a leaky line under the top carb...
