I believe it is your carburetor, which does not get along with your 009. I ran that setting for a while and tried different advances on my 009 until it worked very well after it warmed up. Be careful, there is a point at which the wrong timing can ruin your engine (do not know how to explain it.) I will look at my tech print outs, see if I can find it.
There is a lot of info on the net.
I went back to a stock 1971 distributor with dual vacuums. Some day, when I rebuild my dual 34-ict carbs, I will go back to my 009.
