Is this a fuel adjustment screw and if so how do I make it to where more fuel goes in? Yanmar ym 146

Need more detail about the picture. Have you looked this parts manual over? https://www.tractorforum.com/thread...142-ym146-parts-manual-0ct10-m21500_en.66164/

Looks more like an oil drain to me.

Jeez... good luck with that, based on the information given! Maybe a zoom out on the area where that photo was taken? The YM146 isn't exactly the most common tractor here, today.

Anyone remember when magazines used to post extreme close-up images of common daily objects, to see if readers could guess their origin?

Can You Identify Everyday Objects By These Close-Up Pictures?

You've probably seen all of these things before, but when they're this magnified, things get a little tricky. Can you still identify them?

The Ym1100 is the closest. Inj.pump & fuel should be the same. YM1100, 2Cyl. 3.26L. 14Hp.. The YM146 2Cyl. 3.8L 14Hp.
Limited for sure and I believe the Inj. Pump IP-200 should be correct. YM1100-1500 2Cyl. use it also. ?
