You should pull the head off to see how bad it rusted up so you don't waste your time. If it is only lightly rusted clean up what you can and put the head back on and fill the cylinder with penetrating oil or Marvel Mystery Oil and let it sit for a few days then work the crank back and forth until it breaks loose.

There are 2 long "wires" with springs on them attached to the carburetor. One goes to the governor which looks like a small lever that comes out of the engine.

What does flooding your engine on your lawn mower mean?
It means the engine has been fed too much gas. If you depress the gas pedal on a car or truck many times before you start it, the same thing will happen. A gas engine, whether it is a small lawn mower engine or a truck's engine works the same. It needs a certain ratio of gas and air in order to create the explosion in the piston chamber that makes the engine work.
What causes oil in your lawn mower engine to have gas in it?
You either have a bad float or/and bad needle and seat, which is causing the carburetor to flood. The fuel then flows through the valves and piston and mixes with the oil. The diluted oil will not lubercate and you will sieze the engine.( Not good!)
