r22 engine start up problem

[2fst4u]

im pretty sure im doing everything right, but when i try to start up the r22's engine following the checklist, i have then engine going in excess of 110 revs, then i engage the clutch (which is wierd, shouldnt it be disengage?) and the engine revs drop right down and stall. is there anything different i need to do? autostart works fine, and starting the engine with the clutch engaged (once again, wierd, by engaged i mean, the engine and rotor are connected, not disconnected by the clutch) work fine, its just when i try to do it properly, by starting the engine then letting the rotor connect that it stalls. does anyone else have this isssue?

Is this fsx it is happening in?

yes. FSX with Acceleration (therefore sp2)
