[HSSS427]

I decided first to just re-check the timing as is. I has about 42 deg total all in somewhere in the 3000s. The base/initial advance was well up into the 20s. I backed the distributor around till I had initial at 18-19. It sure seemed to idle a bit rougher at this level, but it was ideling at about 900 rpms. Is this to be expected?

Now I'm going to check for TDC and see if the marks are correct and also see what bushings and advance curves are installed in the MSD distributor.

Will post findings shortly.
Thanks!
