Last year I purchased a rebuilt dist. After having some tune up dificulties I decided to replace the vacuum advance unit ,,It helped but not completely, The other day I removed the points plate and found that the weight springs were two different kind, One was of weaker type and the other was very stiff and sloppy. I've heard of racers changing springs around to get a modified advance curve but getting a dist. from an auto parts store I would think that the springs would be the same tension.
Does anyone know what the standard springs should be?
I replaced them with some new springs rated for 20deg curve but all I could get were for chevy, they seamed to help it run better. But I still dont think its right.
I do have a crappy carb so getting this engine to run tops is rather tricky.
