I welcome comments or suggestions on these 4 exhaust valves. The engine is a Superior IO-320 with roller tappets, dual Pmags, and 400 hours since new.
Please pay special attention to #3 which is exhibiting erratic EGT at idle only. Possible sticky valve? Cylinder #2 also has a half moon mark on the edge that I can't explain.
Obviously, I am new at this.
