I started my Troy-bilt (super bronco) the other day. I almost
immediately started running rough and smoking profusely.
I shut it down and remembered the last time this happened.
Sure enough I checked the oil dip stick and the fluid level
was a couple inches above the full mark. And it smelled
like gasoline. I put a pan under the drain plug, opened the
drain plug and the fluid contents poured out like water and
smelled like gas.

As mentioned, this had already happened once before.
My question is: How can gasoline be getting mixed into
my oil pan ? This same situation once happened to my
girlfriends mower.

I have never mistakingly poured gas into the oil filler, and
I suspect that someone is out to get me - unless someone
can explain a good reason how else this could happen.

TIA

I don't know about this particular motor, but if the float in the
carburetor hangs up, the gas runs into the piston and down the gap in the
rings to the oil pan.

Wow... Thanks Ralph. I hadn't thought about that. I did ponder
" carburetor " for a moment, but not the float valve. In my paranoia
I immediately suspected foul play. I changed out the oil and did
my mow job, parked the mower. Then ran a length of black thread
across the garage opening ( no doors ) and check it periodically
to see if anyone had 'tripped' it. My next move was to be a trip to
Harbor Freight and buy a motion detect alert gizmo ($16.95).
Then I'd fill my S&W 357 with 38 Sp shot shells and wait for my
queue...

Would it help to burn some kind of carburetor cleaner stuff ?

It's a 2006 Super Bronco w/B&S 19 hp if'n that makes any dif.

Thanks again ... ( them shot shells are $15 a box of ten ... too
much to waste ..)

Save your money. I have one and it is too sensitive. Sets off the alarm
in a breeze when a leaf moves anywhere in its field of view. I think it
may detect flying insects too. It set off more false alarms than real ones.
You'll find that you will be disconnecting it during the time when you
really need it for your purposes, i.e. at night.

Hollow points are more effective and less expensive.
You do need to post a warning sign. Goes something like bullets are too
expensive to waste, so do not expect a warning shot.

Adding a fuel shutoff would help. You could run it out of gas before
putting it away.

Another good idea.

I'm not looking to kill anyone over this matter ( if indeed someone is
tampering with my mower ). Just wanna give'em something to think about
while pulling BBs out of their bottom.

I will post a sign.

As Ralph suggested, sounds like it could be the
carb float sticking. You can pull the carb, take off
the bowl and clean it. They have carb rebuild kits
available online, Ebay etc that cost typically $10.
They include new needle valves, gaskets, etc.
The gasket between the carb and intake is usually
not included, so get one of those too. Carb cleaner
and compressed air if you have it to clean it.

I've never taken a carb off nor rebuild one. Is it something an average
person can handle ? I suppose I could google up a diagram or two.

It helps to have the shop manual which is probably available
online for free if you're lucky or for purchase.

First thing I buy when I replace a vehicle is the factory service manual. If it
is not available, I won't buy the vehicle (Kia minivan,for instance).

Im not sure on whats fitted to your engine but in the past i have had trouble with fuel pumps that run off the cam in the engine. The gasket in the fuel pump can perish and leak fuel into the sump. If the float in the carb was sticking open id expect poor running aswell.
