Anyone know where the oil drain plug would be on this Brigs engine?

On a smaller 12.5 hp Briggs

Get a 2+ gallon one so it’s handy for bigger engines[emoji1303]

If it's got a drain plug I use it, because the sump is usually shaped to make the bung its lowest point.  If it hasn't got a drain bung like a lot of modern small engines I'll suck it out with a vacuum pump.   Normally  I find if you suck it out of a vertical shaft engine with a drain bung, you'll find you can't get as much oil back in as you can if drained properly.  That tells you something, or it should.

A threaded drain plug in a sump doesn’t always allow removal of as much waste oil as you’d think
