[TR] distributor advance

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.�� 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 idle� (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?� IIRC, something 
like 0.04" of uncontrolled float can create +/- 5 degrees of timing 
jitter.� You stack (or remove) shims under the dist pedistal to correct 
the end float.
