    Like title states, got a Exmark WB w/ 17HP V Twin - recoil start - hydro - 1000 hours - well taken care of. Ok, here goes..noticed oil like dripping out where muffler connects to exhaust..pulled oil plug, small like gas, drained and was very thin. Cleaned carb very well, put together, ran great one week. Now today, exact same thing. I suggest fuel making it past fuel pump or carb into crankcase case. Can I just replace jet and float in carb..is fuel pump serviceable?? Thanks for any help.

    Don’t know what model you have. Some of the newer carbs use an o-ring style bowl gasket and also other o-rings to seal the body. If you reused them, and everyone thinks they can, they can leak and give the same symptom. As fish states, it could be the pump. You should not have any fuel at the impulse port of the pump.

    I would imagine that has a simple single bore carb. There’s about 100 variations of that model.
    If it is a single bore, it will not have the plastic module in the body I’m referring to.
    Disregard my post.
