you've got some other issue going on.
A stiffer spring would have not allowed the weights to swing out as far
at lower rpms. It would NOT ADD idle advance over the original
settings.ï¿½ï¿½ If anything...your original timing setting might have been
now retarded as the new springs would have held the weights in longer up
the rpm band, and possible at idleï¿½ (new springs= no/less centripetal
advance at idle).
If your timing is bouncing around or erractic...have to bothered to
check the end float of your cam driven dist drive gear?ï¿½ IIRC, something
like 0.04" of uncontrolled float can create +/- 5 degrees of timing
jitter.ï¿½ You stack (or remove) shims under the dist pedistal to correct
the end float.
