Hi Jacob,

I cant tell off hand - the specific make/mode of that sprocket for that 
pedal gokart.
It does however seem to be some combined unit, with the lever (which can 
be seen from the photo) acting as a brake lever, OR as a gear change for a 
"sun and planetary gear". My best guess is that, it is a gear change 
lever. The "sun and planetary gear" is explained here:
Old bycycles with 3 gears used a similar gearing system called "sturmey 
archer". More info on this gearing system as specifically used on bycycles 
can be found here: http://www.sturmey-archer.com/

The chain guard in plastic is covering both the sprokcet and gearing unit 
(or brake unit). If you removed the chain guard you would be able to find 
out some more information.

Is it that the sprocket/gear unit is broken? If you manage to remove the 
plastic chain guard you might see a small ruber "oil cap" on the gearing 
unit (if that is what is combined with the sprocket). You could try 
pouring in a little oil and see if it makes anything a bit better.

Anyways, the best of luck,
