I am experiencing a slight power loss with the 1 pmag/1 slick mag combo.
Have checked timing on the slick and the pmag. Slick is at 25 degrees BTC and pmag set at TDC. I was able to see 150 ktas with two slick mags, now I am only able to get 146 ktas after testing for a couple of hours. I am running full power. I checked rpm drop in flight and got an 80 drop on the slick and a 50 drop on the pmag. Trying to understand the timing advance with the pmag but not sure if that is my problem. What other tests or factors should I be thinking about?
