Do you remember the engine run where we showed you the high ICPs and thetaPP close to TDC when the engine was ROP and not rich enough? As soon as the fuel flow was turned up above the redline, the ICPs went down and the thetaPP moved further from TDC. That is the problem with your front engine. GET IT FIXED. It is very easy to address (one screw) and should be done to lower the heat and stress that engine is enduring.

As to the fact that in twins the FF is rarely the same, that is true... BUT, they both should be adequate, which your front one is not.

The biggest problem with a twin is that you have two engines to *compare* with one another!!! <g>

Many pilots and mechanics will say that this engine is operating too lean. We know what they mean, but that is technically inaccurate as it is still a rich mixture. It is not a lean mixture. It would be less confusing and more accurate to say that your front engine is not running rich enough. Yes, it's semanitics, but it's a rather significant conceptual difference.
