Seeking advice/experience with fluctuating fuel flow when operating LOP. I balanced my nozzles a couple of years ago and had good success operating LOP. Recently, my fuel flow is indicating anywhere from 8 gph to 6 gph after I set the mixture. The EGT is unstable and I can tell the engine is not running smoothly...my guess is because the fuel flow is indeed inconsistent.
I'm planning on cleaning the nozzles and looking at the divider.
My typical cruise altitude is 8500 to 12500.
The OAT has cooled off considerably in the Southeast...I understand a higher fuel flow would be required based on a lower density altitude...but would that contribute to this problem?
What am I missing?
