Adjusting the timing on a NS40C

Hi all,

Having trouble understanding exactly what needs to be adjusted when trying to adjust ignition timing. It appears that the timing link needs to be moved forward in order to line up the match mark with the fitting line (see photo). In order to do so I think (but not sure) that the nut on the timing link needs to be turned. Also the service manual does not do a great job at describing where exactly how and what needs to line up with the marks on the flywheel to set my engine to 25[SUP]o[/SUP] BTDC and ATDC 2[SUP]o.
