EMVaos - read above :)

You can save the flight and the state of the panels to avoid losing all your preflight work, then restart everything and see does it reoccour.

Have you tried starting with default engines running? Does it wotk then?

May also be a problem of control axis assignments for the engines... Is it only one throttle lever?

Just did a flight at Area 51 CLD/DRK and both engines started fine and thrust moves.. Werid - if it happens again on my flights ill be sure to post it!

same here, some times happen some times not. Also if the hydraulic pumps b goes low pressure for a long time it would not get eninge 2 started at all

I have had this happen on 3 engine starts. I've not managed to find a workaround. My default flight is set to the trike. The thrust works fine when loading the aircraft up for the first time but as soon as I load the cold and dark state and get to the point of after star there is no reaction from my no.2 engine even though it has successfully started. Is this a bug or am I not doing something correctly?

Check this out, it happened to me too (still does sometimes) http://forum.avsim.net/topic/341688-no-thrust-when-moving-thrust-levers/

Fella's this is just a problem with FSX, I've encounterd it numerous times in all kind of stock and add-on aircraft. The only solution I'm aware of is reloading your flight...

Before i reinstalled NGX to fix another problem, I experienced the issue also. Im running W7 64bit and using the logitech 3d Extreme pro joystick.. By chance I had the issue at NZWN, NZAA and NZQN! EGT was 367 and N1 was locked at 20.4 - exactly the same as in the above screenshot..
