I've been using a UMI #2 on my 183 recently. I didn't expect it to work, but it feels pretty good to me.  
When you say "B and C", you do mean B natural and C natural, right?  I don't seem to have problems there, but I almost always play Bb and F on the 4th valve.  1+3 don't cut it.  Just now thinking about it, the C is 1+2 and the B is 1+3, normally.  Have you tried C as 1+3+4 and B as 1+2+3+4?  It occurs to me that those should be correct fingerings with 4th valve, but I haven't tried them.  I'll have to go try it...
