Yeah, and suggest you download the EMag manual. It has this and a lot of other great info.My 390 came with two E Mags and Denso IKH27 plugs. They were gapped 0.030" from Lycoming. I presume this is correct, but I can't find anything in the Lycoming manual on this.
5-10 is a big jump. Just curious why so much in your view? CHT purposes? TY! -GSuggest Jumper in and retard 5-10 degrees from '0'.
