my understanding of mechanical advance & vacuum advance, tell me i'm wrong

[vector1]

no, this is a hei clone. got it fixed though, no problems so far.

couldn't use the msd bushing cause the posts have a shoulder, but needed to limit the travel some, so went to hardware store and bought a piece of thin round tubing to slip over the shoulder, bout all that will fit, put weights on from msd unit and used lightest springs. figured between the vacuum advance and light springs advance is going to be all the way in at all rpm's anyway except when starting it is at 12. checked total mechanical timing and it was at 34, go figure (got lucky). advance at idle with vacuum attached is little over 30 so it's prob putting 18-20 in, don't know what they are supposed to be at.

think i'll go have a smoke now, cept i don't smoke.

thanks for the sanity support.
