I'm baffled! Started with the obvious by replacing the plug. Then I replaced the coil certain that it would work. There's nothing left in this circuit. Flywheel looks intact.

Did you set the coil air cap to specks?
I use a playing card.
Not trying to suggest that you are clueless but I don't know how much you know or what you have done. So don't feel insulted
It's a simple Ryobi push mower with Tecumseh motor. There's a kill switch with brake and nothing more that I can tell. Magneto looks like it's ok. There's a light smell of gas on the plug after I pulled it.
I am using the new plug grounded to the cylinder to look for a spark.
The new coil was installed using the business card method.
Since the covers were off, I used a rope wrapped around the metal cup on top of the flywheel that normally engages the pull rope. I could not see or hear a spark.
Is the spark so faint that it can't be seen with a gapped plug?

It is hard to see in daylight, also, put the starter back on to test, you may not be rotating it fast enough. Take it in the garage and turn out the lights.

You have nothing else left to try. Either one of the new parts you have installed are bad or as Fish is saying you aren't turning it over fast enough. Put the engine back together and then see what you get.
Two common mistakes to check. One, is the coil installed correctly? The kill wire terminal must be down, close to the block. Second, with the starter off are you spinning the engine over in the correct direction? Either one will not produce a spark.

And in post*6 you say "Magneto looks like it's ok." did you replace with a new one..?
Are you sure the engine brake is releasing fully,and the exhaust is clear ?
Also,make sure the plug wire cap is connected well,to the wire. A bad crimp,or the wire not making contact to the cap could make a weak spark,as could airgap being wrong.
