Glowing headers

RustyRatRod said

Glowing headers is an indication of retarded timing first. With the timing being late, the fuel is still burning leaving the cylinders, because the ignition is started too late so it continues to burn. This reacts the same as a lean mixture, since all of the fuel is not burned inside the chamber. Bump the initial timing up.

That`s why in my first post I was asking about timing. My search here on fabo come up with about 8 threads on glowing headers and a couple fabo builders telling them to put in more initial. My thread comes up with a lot of too lean-jet it up. So maybe I`ll try again with about 18-20 initial, before jetting. This is nerve wracking to me. ha
