I believe he meant 90 degrees as in perpendicular, not temperature.

Having 4 honda engines now, I can assure you that each and every one has a drain plug. Even the newest only a bit over a year old and the cheap Honda (GCV) at that. They are on the side, not the bottom.
I will do some research on the local dealers on cheap mowers as one without a drain plug is too "out there" to accept without checking.

Probably. I jumped to a conclusion.

I can verify that not all Honda engines have drain plugs. Not on the bottom, nor on the side. I have a small hand pump that pumps the oil out thru the fill hole. Tipping on its side could hydro-lock it (oil in the cylinder).

Of course, I meant "tongue-in-cheek".
How much oil do you think would pass the piston rings? (not much) How easy is it to correct for oil in the cylinder? (Very easy)
I'd rather get a complete oil drain, and risk the oil in the cylinder.
I can assure you that mine doesn't. The instructions say to tip it over into a pan to drain the oil. I was very disappointed in Honda for such crap in an $750 mower.
There are *many* tip-overs.
I didn't tell him everything. I do that too often, spoon-feed someone. He'll figure it out when the gas starts to pour out. (That's why I said to do it on the grass, not the sidewalk, although I didnt' actually think about the gas. :) )
Take the gas cap off and cut a piece of cereal box for a gasket to plug the gas cap ,dump oil. If you do spill some gas drop your joint on it,it will burn off.

I scoop them up with a shovel and drop them down the post holes I bought on e-bay.
Wow. It's been 45 years and I forgot that. (I never drained or changed the oil sine I move here.
Good points. Thanks.
P&M because it's been a couple days.
Of course here the idea is to get rid of the bad oil, not to run the engine with it, but otoh, I guess 10 minutes won't hurt.
0t3h, sludge in the bottom isn't what he's trying to get rid of, just the stuff that was added a couple days ago. And the mower is only about 3 years old, so it doesn't have much sludge, I think.Thanks to you and everyone.
I will also remind him about taking off the spark plug wire, and putting it far away from the plug. That's a safety issue, and some people don't realize that the spark can jump a half inch or more when one pulls the rope.
And when the blade is turned from the bottom, that's a lot like pulling the rope. Maybe it can start the engine, and for sure the compression can cause the blade to kick back. Removing the spark plug eliminates the compression, but I don't know if I woudl do that just to change the oil, which takes only a few minutes and one should be able to avoid pushing the bladee or pulling the rope during that time.
Thanks.
I was speaking of general maintenance...not about the OP's question, specifically.
Two cycle oil is often 30 weight. Many two cycle oils list the viscosity on the label. Should run fine, even if left in there. The advantage is that any oil that gets past the piston rings won't smoke as much when it burns.
To get oil out of the cylinder. Remove the spark plug, and pull the start cord (or turn the starter). The oil comes flying out the spark plug hole.
