The reason I wasn’t positive if that was i was about 0.050” of slot opening making an approximate square skit visible as seen by the picture I posted previously. From what I understood this was perfectly acceptable BUT I am not running a stock engine. So maybe other rules of thumb just don’t apply. In any event the cold plugs, lack of air is a problem and opening up the secondaries 0.030” makes sense to me. I just wasn’t sure what the secondary transition slot was doing as I did read somewhere that they too should be slightly revealed. BUT this has been challenged by people here with way more experience that I respect.
