i can understand your feeling of tilting over a snow blower, impossible, that's why they have drain plugs, tool less fittings or extended drains.
my tilt it over is a kawasaki on on cub cadet, there the shop manual even states tilt over to drain,or suction out, just like many lower priced store lawn mowers. this is more a epa thing to help waste oil go where it cleanly belongs and recycled!! the days of drain plugs are going BY-BY!! get used to it.
as to the suction way, if you look at where a drain plug sits on a lot of machines,it is above the oil pans lowest spot. again i take my lt1050's cubs 25 hp twin kohler into account, there is always about a half quart left when i refill it, after using the tool less drain, the drain is above the lowest part of the pan, still makes one jack one side of the machine up to use it , yet if i suction it out when the engine has been prerun to heat the oil to about 100 degs, the suction tube is all the way down into the pan bottom and i refill with the 2 qt spec.
oil change wise take a IO or full inboard in a boat, How do the marine techs change the oil?? SUCTION!! it's the only way save some brands that have a hose in the pan that pulls out of the hulls drain when the boat is out of the water, again there is oil left over in the pan, suction again the tube reaches all the way down into the pan, what ever is down there comes out, not left behind some baffle in a cast pan like on many small engines today,
when the cat service center comes in to service the twin cat c15 acrerts in my 48 foot ocean ss boat. they suction out the 36 qts in each motor ,same with the marina that services my 23 searay's 454 IO, while in the water, suction!
your 4 stroke weedwacker. yes i know they have that red screw in plug that serves both drain and fill, since the machine is so small the only way possible . what else can be done,pickup the tool tilt on end drain out the 6 or 8 ounces ,refill
again i was a auto ase gold master tech, what we did 30.40 and 50 years ago ,is no longer is correct,
