So I just bought an Olympia SM2 yesterday and it works amazingly well. Prints well, type action extremely smooth. The only issue I am having is the backspacer going back two spaces instead of one. I have noticed a linkage that is threaded and has a locking nut on the right side of the machine. Is this what has to be adjusted?

I wanted to ask before I got too deep into a excellent working machine and some how mess it up!

Thanks in advance. OliverNo.9.
