Thanks for your time folks, I fixed the problem, I determined that; when I configured throttle the thrust travel was not going the full length of its travel. It was stopping at about 60%. I then, configured the throttle using the second method, using buttons VKB recommended. Finally the 2 triggers or pull levers in front of the throttle work. I use the hold reverse throttle instead of toggle on/off.
I wish to Thank You all for your interest and help.
