I'm having an issue with the startup process.
When I'm starting up engines, Engine 2 always seems to be running fine, but Engine 1 struggles. When I start #2, I wait for N2 to reach 20%, then I introduce fuel. N1 gets to about 17.1, EGT to 495.
However, on Engine 1, I get about MAX 13.1 N1, 14 EGT. And when I advance throttle, they both fall.
Startup procedure is same for both. What is happening?
By the way, even on "Start with Engines Running", and no failures, Engine 1 always does this.
