How did gas get in the oil in a Briggs stratton 8.0 HP engine?
Most likely the needle valve & seat in the carburetor bowl is defective allowing fuel to flow when the engine if off. This excess fuel will run into the cylinder and down to the crankcase. Replace the needle valve & seat.
Why is gas leaking into the oil of my Briggs and Stratton 25HP model 445777 filling the crankcase with gas when the mower sits?
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.

Fuel pouring out the air filter on your new Toro mower?
The float needle valve is stuck or there is some kind of debris that got into the gas and is blocking the valve open. If its a new mower take it back to the person you bought it from and get them to fix it because it should be under warrenty. If you mess with it you would probably void your warranty.

How do you adjust the carburetor on a 6.0HP Briggs and Stratton lawn mower engine?
If the engine does not start: (1) rotate the carburetor main jet needle valve clockwise (close) until it touches its stopping point - DO NOT FORCE OR GO BEYOND THE POINT OF TOUCHING as it may damage the tip. (2) Rotate the needle valve counter-clockwise (open) 1-1/4 to 1-1/2 turns - this should be close enough to start the engine. Start the engine and let it warm up about five minutes. (3) Rotate the needle valve clockwise (close) slowly until the engine starts to stall for lack of fuel, then rotate the needle valve counter-clockwise (open) slowly until the engine starts to stall from flooding (too much fuel). (4) Set the needle valve to a midpoint between the two extremes for the best "purr" of the engine. If the engine "sputters" when a load is added, open the needle valve an extra 1/8 turn for a slightly richer mixture. If the engine starts and you just want to adjust the carburetor, step (1) is not necessary.
