non starting engines

[coreservers]

I have a couple of planes, the antonov an2 and tupolev Tu134.
they both look fantastic, but when I select a flight plan and load to teh airport, they both cut out engine wise. I press control E and the engines wind up, only to cut out again. anyone any ideas or am I missing a control key, with my old eyes
I've tried with a little bit of throttle, no throttle full throttle!!

Ensure mixture is at 100%.
For the An-2 in FSX, you have to modify the starter strength in the aircraft.cfg. The parameter to increase has an explicit name, you can't miss it.
