Model does not start engine.

[mariomotta]

hi all,
a weird thing happens, a model that starts engine perfectly on FS9 does not start in FSX even if i use CTRL+E, auto starter mode.
I could port all the model, textures, gauges in xml, etc.. working except i cant start the engine.
The only solution i have found is to start engine with another airplane and then change to my one.
On air restarting works fine, i suspect that the starter does not runs the engine above the required rpm to start, even if brings it near to 20%, but do not know where put my hands.
put here aircraft.cfg lines that could be of interest:
