I just worked on a K 950 at work last week and noticed the same problem with it not sealing good between the intake and carb.   I used some Yamabond on the surface and that seemed to work.   I was told the intake was NLA.   This particular saw uses a special bar and chain for cutting concrete.  I have never seen another like it.  The saw also had all three clutch springs broken which I replaced.  The business I work for actually had those in stock.  When done the saw seemed to start, run, and idle ok.
