71 LA 340 timings moved!! how?? looking for help

Umm the silence is worrying lol!! anyhow today at long last the rain stopped so I could uncover the troublesome Duster.. I ended up pulling the dist altogether and found??.... totally nothing that seems out of place, shaft is free spinning with ease, weights in place springs in place, its pretty stiff to get them to move but they do move free, the vac seems to be seized but its disconnected anyway... I'm really getting to the end now :-( I'm guessing the issue is not ignition related at all.. since bringing the timing back to 17 it no longer idles once warm, its getting too warm IMHO, although temp gauge says all is fine, when I restart the start starts slow as if battery is dying, but its not.. so I guess advance timing back to silly numbers so I can at least drive it the 5 miles to long term store.. anyway here are some pictures but they tell nothing.
