I need to drain the coolant from my Universal M4-30. The drain plug in the photo I have from the manual is near the dip stick on the side of the engine I can reach but can’t see. The photo in the manual is pretty useless as I can’t see what it is pointing to. Does anyone know more precisely what it looks like (size?) or a way to find it by feel (or another way to drain)? Thanks- Dave
