Putting a little Oil in cylinder before initial start of new small engine.

What are your thoughts regarding placing a small amount of oil (1-2 tablespoons) into the cylinder through spark plug hole and pulling the pull start to prelube the cylinder prior to initial starting of the engine. I have heard that some people recommend this as it can lubricate the cylinder walls, piston rings, etc. What kind of oil do folks recommend? Regular engine oil?

Make sure the engine has oil and it is at full mark. If you want to add a little oil down spark plug hole and crank it over a few times, nothing wrong with that at all. Remember that long term engine longevity for your engine is regular maintenance including oil changes, checking oil, and watching the air filter to keep it clean.

Have never done that but sounds like a good idea. What about fogging oil? Take the plugs out turn each cylinder to BDC and treat it with the fogging oil. It would be much easier to get it into the cylinders. Just a thought.

New engines from the factory already have assembly oil coating all of the internal engine parts before the crankcase is initially filled.

To me it is not necessary to put oil in a cylinder that will likely disrupt the spark plug from firing.

Proper oil level and changes from day one is the life of any small engine.

Never a concern about getting all the break-in metal out. Every new or rebuilt engine will have a ton of metal flake in the sump.

Yep,

I had to tell a customer recently to quit flipping his push mower over to sharpen the blade because that old break-in sludge would kill his engine. He would not listen to reason, so it cost him an engine in one season of mowing.
