Eliminating hot starts

Could someone please help me with the Kittyhawk 738 - no matter what n2 value, minimum or maxed out, when I flip fuel on the engines surge to near full power before rolling back to idle. I've tried both the original and Mike Baumann's fdes - same thing.I think I read somewhere once what value to edit in the aircraft.cfg or .air file, but don't remember now....unless of course this is normal?Any help appreciated - I've searched as best I can.regards,Markhttp://i14.photobucket.com/albums/a319/markrey/lsd2.jpgXPHomeSP2/FS9.1/3.2HT/1GIG/X700pro256
