I have FSD's C337 and love it. Last night, I was flying the C337H, the high altitude version from Banff to Seattle. Since there was snow and heavy clouds, I had all anti-icing runnning. I was tryong to climb to 14,500 ft. but at 13,2000, the plane got very sluggish. I dropped back down to 13,000, but the engines were still running slow and unevenly. Adjusting prop and mixture had very little effect.
RPMs kept dropping until I had no alternative but to find a place to set the plane down.
I realize I probably forgot to set something properly, but can't for the life of me, figure out what. Any ideas?
