Throttle and Jet

Please, I need some expert`s help!
I am pretty new in the bussinnes, flying planes on FSX. I have no more problems to handle a smaller plane. But when it comes to a jet, it becomes serious.
What can I do to control the throttle, to get a smooth axcereration like in a prop?
My Learjet, e.g. "jumps" to 50% power when i move my throttlle, starting from zero power. Even taxiing is impossible.
What am I making wrong?
