We are getting way off topic here however when I open up a vertical shaft engine and see a lipped ball race on the lower bearing rather than a thrust washer taking up the end float sitting on the bare case, I will change my opinion. Or even a radial roller / ball carrying the weight of the crank with a roller on the top to take the latteral load levered through the crank.
Remember the crank is being pulled by the drive belts and this force acts as a lever on the crank with the fulcrum at the lower bearing and the resistive load at the upper bearing.
Horozontal cranks can & many do have the crank case joint along the line of the crank which allows for self aligning ball baring to take up the end float rather than doing things like fitting thicker gaskets to adjust end float.
And yes Honda used to make a lot of vertical engines which were the top line but they only do the small push mower engines now.
Kawakasi moved in to take Honda's place but they are doing what Honda refused to do , downgrade their product to a price level that the "market" will pay.
Talk to any one who repairs engines and they will tell you the quality is on the decline.
