Check your battery, Rotorboy. If you have bad battery, you need to move your fuel control more forward during start. It great's of course T4. Be aware it. Change your battery ASAP if it's the fault.
(That you need to do only if you are in the middle of nowhere!.)
Normally I'm doing my starts like this: Move forward fuel control when it's front edge is front edge of the hole. (I mean hole where fuel control is during flight) Then push start button and t4 rise to about 670 degreeses after Ng is thru 10%. You dont have to move fuel control before t4 is going to fall. Keep t4 between 650-700 degrees during start. That is easy way. It works our As 350 B and B2 helos. (Still monitor T4 all the time!!.)
(hope thet you are understand what i'm trying to type) Languages are not my best part.
