Concur 100%
Drain the Gas/oil mixture, and change the oil and filter if equipped,
( IIRR they have filters)
Glad it did not start for you, as it could have caused engine damage.
As mentioned,
it could be just a fluke, that a piece of crud got under the needle valve in the carb, or it's time for a replacement of the needle/seat.

Also as mentioned, the fuel pump diaphragm over time, becomes worn and it leaks allowing fuel into the crankcase, both are common problems.
At the age of these engines, it is good preventive maint. to replace the fuel pump and the needle and seat in the carb and be done with it.
The plastic pump Kohler now sells, although a bit pricey (shop the 'net)
is a good pump, also Stens is another good aftermarket pump.
Some of this chi-naww stuff is questionable.

When you get the electrical problem solved and it is started for the first time,
it will smoke like a steam engine pulling a grade, till the oil/gas mixture gets out of the exhaust system.
You will have spark plug fouling during the initial start up most times.

I suggest that before the first start is attempted, one should spin the engine over with the spark plugs removed to purge most of the oil/gas mixture out of the cylinders.
Be careful that the spark plug wires are kept away from the plug holes as the fuel mixture you are purging is Flammable and it only takes one spark to make an "oh shit" moment,
Also it is a good idea to install a fuel filter while working on the fuel system if one is not already installed.
Keep us posted
