Mine was doing the same thing, and it turned out one of the plugs was not firing, which turned to be not the plug but the coil for that side (Briggs & Stratton 18hp on an MTD 1650 lawn tractor)
I have a 1996 Cougar XR7 that was leaking, and it turned out it was the intake manifold. Was leaking in front of the passenger side on the back. New one was 480.00. Dang car has always had a leak somewhere since it was bought new.
Out side in the lawn
The best way to mow your lawn would be up and down and side to side

Either one of the heater hoses are leaking or you have a freeze plug on the side of the engine leaking.
i have 8 hp horiz. Briggs leaking at the mail seal, flywheel side. I put a new seal on but it still leaks. I suspect too much crankcase pressure, maybe the breather is not open enough? anyone got some ideas on this? when I turned the engine by hand without the seal present, lots of air vented out the oil drain hole behind the seal. that is why I suspect high pressure. Is this normal? it runs great but leaks out the flywheel side main seal. ms
