A local store used to have a sign on their door:
If that doesn't work, PULL
If that doesn't work, we're closed.
So, if you turn both adjusting screws counterclockwise the same number of turns and the chain loosens instead of tightening, reverse course.
Don't trust the axle position markings on the swing arm. Carefully sight down the chain and rear sprocket to see that the chain looks straight on the sprocket. Roll the rear wheel by hand and see that the chain isn't always on one side or the other of the sprocket. The sprocket is held in the wheel hub by rubber "absorbers" and has some play, so it won't be perfectly true.
