On each cylinder there’s a plug screwed into, I
presume the water jacket. However, the low
spot for a drain on the cylinder, would appear to
be the lower cooling line.
Any idea what the plug is for? Doubt if it’s been out
in the last 66 years, so I’ll leave it alone unless
there’s a really nifty reason for it!
George, that was my conclusion too, but curiosity
always gets me in trouble, lol.
Had to be a reason for it at the factory,
but that reason was probably locked up, and key
thrown away!
