    Oil blowing from fuel pump
    I have a Briggs & Stratton Intek 18 HP engine (31H777-0202-E1) it is about 11 years old on a Gravely mower. When it runs oil blows from the fuel pump at about and ounce every 10 min. I've replaced the reed valve in the carb and replace the fuel pump and still blows.

    Do you have the right amount of oil in the engine? What does the spark plug look like? Have you run a compression test?

    Yes, the oil was just changed before it started, the plug was clean and plenty of compression. Had someone test it.

    I am not completely familiar with this engine but in general, oil blowing from places it doesn't belong will often indicate bad piston rings.
