SailerMan, I don't have the SX/B documentation, but:

1) I assume your SX routine is happy with mode 0 (MSBPRE)

2) I assume that your SX routine expects Data on RB.1 and Clock on RB.2

3) On the Propeller, have you set "DIRA[19] := 1"?  It won't work if you don't.  You should probably set "OUTA[19] := 1" just before that to ensure that the SX won't see a zero too early when the pin becomes an output.
