RTFM, OK I get it

Found enough web info to determine that the spring in the vaccum can is in fact all there is to return the dist back to the non advanced state.
I've determined that I'll need to replace both the vaccum can and the line (if the double flair doesn't seal).
Also the starter crapped out.
Picking up the brand new exhaust pipe and rebuilt starter today. Hope to restart & fine tune tonight.
