distributor springs light enough ??

Update


worked on the dist curve today and installed one real light aftermarket spring for the weights and the other is a oem light spring . started it up and set it for 34 total and it does not advance anymore now .. Which is good! before it kept wanting to creap up past 34 total..

only thing I see now is that when it's idling , i see the timing mark jump way up for a second and back down to 18 initial. It must be right on the erge to start pulling that other spring open ??

It idles real slow and smooth ...like 700rpm

should that be of concern .. it idles great it is not missing a beat and the idle stays right there and does not change .
