Timing drift (a.k.a. spark scatter) is not a result of weak distributor
springs. Weak springs manifest themselves as overly quick advance. Most
often, the cause of spark scatter is worn distributor bearings.
Unfortunately, the easy fix for this is to replace the distributor. It
may be possible to replace the bearings in the B dizzy; I don't know.
On the bright side, spark scatter will not strand you. It will cost you
power, mileage, and driveability, but it really can't get bad enough to
shut the car down cold.
Hope this helps-
