    Briggs and stratton engine 18.5 runs bad
    18.5 intek b/s engine.
    Sometimes hard to start, when running it smokes out exhaust.
    Also smoke coming out of fuel pump vent hole.
    Runs better at full throttle but w/more oil from fuel pump coming out.
    Oil level is not overfull, any solutions?

    What is a Fuel pump vent?

    First thing I would do is check the valve clearance?

    Sounds like you have a gasket or seal leaking some where causing too much internal pressure.the fuel pump works off engine vacuum.pressure is forcing oil through the pump breather vent,
