Am I the worst newbie or is my throttle really not working?

Sorry if the previous post came out garbled, I intended to say that again today after no joy on the first 3 tutorials and free flight in a Cub I tried a Cessna CJ4 jet and the throttles seem to work ok, got screenshots of N1 at 20% and 60%. Still re-learning to fly in twin jet engines would be a steep learning curve so as much as I am pleased that the effect of the bug may be limited i would edfinitely like to sort it.
