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

Slomo, you better read a couple of owners manuals for today’s walk behind mowers. Most of them recommend changing the oil by tipping it on its side with the carb up. Just because you don’t do it, don’t make a blanket statement that it shouldn’t be done. Second, purchasing an evacuation system is not cost effective for the average DIY guys out there. The one you show costs well more than $125.00, how many times do you need to use it for the average guy to justify that cost? When posting remember your audience.
 
1-2 Tablespoons?! Holy crap, man. Good luck getting it to start! That is waaaay too much oil. I use only a thin film of oil on the cylinder walls when I'm putting the cylinder in, that's all you need! Use a tablespoon and you'll basically choke out the combustion and it won't start.
 
If you want store an engine or give it a little lube to stop the supposed dry start they sell a product called fogging oil. Made for storing outboard motors. Remove the plugs and give a couple second spray in each cylinder and cank starter for a couple seconds and put the plugs back in.

Cosmoline for the old timers. Close to a wax so not great if it dries out completely.
 
Cosmoline? That stuff is an oil wax takes solvent to remove. That was a storage compound made for external applications mostly on rifles, then they were wrapped in heavy wax paper.

It has been adapted to automotive parts, but very strategically applied.

I would not risk that stuff being put in an engine cylinder.

I tip over every push and self-propelled mower that I do an oil change on to drain the oil. I think some people are overthinking this whole deal. Not uncommon at this point for the customer mower to have black, old oil that is either overfilled or barely on the dipstick. Never had a problem or a comeback from doing it this way.

The whole point of a mower is to cut grass and do it as cleanly and efficiently as possible. Sharpening the blades is important. Many of the blades I see from customers are beat up and even need to have the angle re-established, and the chips be taken out.

Left out an I for "I" never tip........ Corrected. No blanket statement meant.
