Worn small freewheel cog
On an 80s mtb, I've got a 5 speed suntour freewheel in back. It has a nice wide range. New replacements come with much smaller big cogs so I am wondering if there is a way to just replace the small cog?. as it is the only one that skips.

Yes, But.
Suntour made a bunch of different models over the decades. You need the model and luck.
these parts have been out of production for decades.
often a complete freewheel will be less expensive or near equal with the labor / tool /cog expense.

Even cheaper, and you can start today - avoid using the smallest rear sprocket with the middle or small chainring. For greatest small-sprocket life, shift to the large chainring rather than always going to the smallest rear sprocket.
In other words, instead of riding around mostly in the small in back, use the middle sprockets in back and the large chainring.

when I started racing I was shocked to learn that the Maximum gear I could use was a 44x14. 84.9”
took some adjusting to that.

Calling Pastor Bob. He may well have the high gear cog you need. Removing it requires a freewheel vise insert and a chain whip, both of which can be found on eBay.

IF you can't find the vise, a second chain whip should suffice.
