Hi George, 
The commutator looked a little knackered on your genny.  A pro would have a
cutter to turn the comm down, kind of like a lathe.  There are also special
stones you can use, but you can use some fine garnet paper to clean it up
pretty.  Emery cloth is not good choice for this. 

The mica is high, as well.  Again, the pros have special tools for undercutting,
but you can make something up out of a piece of tool steel.  Make it like a
scraper, and then very carefully scrape the mica until it is lower than the
commutator bars.  

That's where I'd start.
