I wanted to post this on this thread too in case someone else runs into this it will make the search for an answer easier.

The Captain Sim 727-100 and -200 series works perfectly with FSUIPC. I got this problem figured out now with the help both Captain Sim and FSUIPC support.
There is nothing wrong with Captain Sim's gorgeous 727 series.  The fuel cutoff switches were locked up because they had settings that were wrong within FSX and FSUIPC.  This was causing a conflict and locking the levers.
The fuel cutoff switches are set with "Mixture1 Rich, Mixture1 Idle" etc. and the same with #2 and #3 within the registered FSUIPC program.  "Rich" is fuel on and "Idle" is fuel off for each lever.

I went into FSUIPC program and set those to the buttons below my throttle levers on my CH throttle and they work Perrrfect now.  I can start up my engines like a pro. 8-)

Again Thank you Captain Sim and also Peter Dowson for your help and for making my 727 so enjoyable. ;)
