How to adjust tuning dial indicator on Pioneer SX-780?

I am the original owner of a 42-year-old Pioneer SX-780 receiver.
Although I rarely used it to receive radio stations after the first decade, I am now interested in reemphasizing this original purpose of the receiver.
However, I notice that my tuning dial indicator no longer aligns accurately with the station frequency I am trying to tune in.
For example, 94.7 tunes in at around 93.8.
Further, I notice that as I turn the tuning knob, I encounter spots where the indicator seems to hang up and not move as quickly despite my turning the knob at the same rate.
I figure that the tuning string linkage probably needs some sort of "tune" up.
Has anyone else tackled a similar problem?
And if so, what methods did you use to address it?
I would prefer not to have to restring it ... but whatever it takes.
Thank you in advance.

The service manual is available here on hifiengine; go to page 13 for dial cord stringing. You should not have to do a whole restring though; remove the front first. You may just need to put another loop in the string where it attaches to a peg, thus tightening it. After that, reposition the pointer; the instructions show the start point (lowest frequency). The pointer is sometimes glued so you may need to remove the glue with acetone or just by scraping it.

Thank you.
It doesn't sound too intimidating.
I'll take a crack at it and let you know if any questions come up.
