Ryan,

You can move the choke from open to closed and nothing happens?? That sounds
unusual.  Closing the choke on many (not all) engine will kill them with
extra fuel.

Do you get any black smoke?

I can see the warm air intake and confirm that it's working.  Cross over is
the only thing I can't trully confirm, I know the thing moves but I guess I
can't confirm that the flapper is completely intact.

The choke, I've sat there and moved the choke by hand while it was sitting
there and it didn't change anything, still ran just the same. (this is while
it was acting up).  Seems to me it should do *something* shouldn't it?

Also, it does seem to be running rich (to me) when it is doing that, at
least not burning all the fuel it is getting.
