Both should move up and down, quietly and reasonably fast.

If a window does not work, this most likely means a bad motor, but check the fuse pane...

Interesting....Good explanation above, but....

Everything I've heard is SBC's need and have full-advance set by 3000 rpms. Of course, I ignored that myself. But, only a hair. I added 1/2 deg or maybe a whole degree by the 4800 mark.

It seems logical to assume more advance is necessary as the engine spins higher and higher,,,but more than one person has said no.

Any more info on this?


Really every engine is different as to how much timing it can take at a given RPM.

No matter what, you eventually reach a point where it lights the mixture off as correctly as it's gonna get.... Sicking more advance to it just hurts.
