[DeTomaso] Timing Adjustment Strangeness

[Forest Majors]

Dan,

Inspect your weights first, because if they are corroded or rusty from non-use they will stick and not perform their function. The springs are color coded but I doubt that they would be the source of your problem. Use some light sandpaper and then apply a thin coat of WD-40 to your weights - see if that solves your problem. This would be a good time to consider what spring combination you should use to set your advance curve for this specific engine.

Good Luck

  Check this out, I had the timing set at 18 degrees advance at idle, then revved to about 3,500 rpms and the timing advanced to about 35 degrees, and then stayed there even after I returned to idle. The hold-down clamp was completely tight.
  I reset the timing to 18 at idle, now it still advances with rpms, and is returning to 18 degrees at idle.
  Does this sound like sticky advance springs on the MSD distributor?
  If I recall, aren't these springs color coded? So I can just see what color I have to order replacements?
