Briggs and Stratton Front Tine Tillers may leak fuel due to several reasons, including a damaged or worn fuel line, a faulty fuel shut-off valve, or a defective carburetor gasket. Additionally, loose connections or a cracked fuel tank can also contribute to leaks. Regular maintenance, including checking for cracks and ensuring all connections are tight, can help prevent fuel leaks. If the problem persists, it's advisable to consult a professional for repairs.
To tip a Briggs and Stratton mower safely, make sure the air filter and oil cap are secure, and tilt it with the carburetor side up to prevent oil leaks. Avoid tipping it too far or for too long to prevent engine damage.
Leak down test : Uses 70lbs pressure to test for leaks around valves and cylinders.
The most common place for oil leaks is the sump/crankcase cover gasket. A torn gasket will allow oil to escape. A common cause could be a blown head gasket putting too much pressure in the crankcase.
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
it is probably your water pump
If a 1980 Pinto c3 transmission leaks from the front, adding stop lead fluid might help. This can be obtained from retail auto part stores.
I hav e the same problem
The front transmission line leaks, how do I replace it?
Replace the front seal which is located by the spline.

If the front of the engine leaks coolant there is a blown head gasket. This requires immediate repair as it can lead to a blown engine if not managed appropriately.
From looking at discussion threads, it seems that B&S engines are notious for this. The carb needle valve is dirty and fails to seat properly, thereby allowing fuel to leak into the cylinder and down into the crankcase. Have your local small engine shop clean and rebuild your carb and install an inline gas shutoff valve. When the mower is idle, simply turn the valve to the off position to prevent any further fuel leaks.
