It is normal for a little gas to be present in the oil. This is why it is important to change the oil at least once a season. If there is a lot of gas in it then I would say that the carburetor is malfunction or isn't properly adjusted. Too much gas flow and it leak into the oil.

Answer #2:

On my riding mower, the problem was originally caused by water in the fuel. This can originate from your local gas station, or in my case a gas cap with a "fuel gauge" built into it, which eventually allowed water to leak into the tank.

The water settles to the bottom of the carburetor float bowl, eventually rusting the float needle, which no longer shuts the fuel off completely. This allows fuel to drain into the crankcase and contaminate the oil.

My solution: Drain and replace oil. Clean float needle until it successfully shuts fuel flow off (or replace needle if necessary). If you have one of the aforementioned "gas gauge" type fuel caps, toss it and replace with a standard vented cap. And MOST IMPORTANTLY - if your mower does not have a manual fuel shutoff valve, install one ASAP. They are available at any mower shop for a couple bucks. Simple inline installation, just cut gas line in a convenient location and plug the valve in place. Now you can shut the fuel supply off when not in use.

Of course, I figured all this out AFTER I replaced the connecting rod and patched the hole in the block!

Why will the engine only run when you pour gas in the carburetor of the Briggs and stratton engine?

if the engine only runs when gas is poured into the carb it is generally caused by plugged jets and/or stuck needle in the seat. if it has been sitting for a length of time the fuel has either crystalized causing the plugging or the ethanol has caused a problem. if it is a new unit, briggs recommends tapping the carb lightly with a hammer to loosen the needle in its seat. for one reason or another the engine is not getting fuel through the carb
