<div> <font size="3">Two things determine how a spring behaves; the spring rate and the free length. When swapping in a longer and stiffer spring will give you more movement initially and less change as the speed increases.</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">So, yes, a longer spring will give you more initial advance at idle but max advance would be achieved at a higher speed.</font></div>
<div><font size="3"><br>
</font></div>
<div><font size="3">But the answer is: It depends. How do the two springs compare in both length and spring rate.</font><br>

The heavier springs are also longer than the old ones, so the

<div>Having studied this over and over again, even have gone as
far as redesigning the whole timing system (during a F.I and
full wasted spark conversion)� ... and with simple physics
behind me I can comfortably say your empirical data has to
be flawed....no nice way to say it.</div>
<div>simple physics.... a tighter (stronger) spring will not
extend as far as a lighter spring under the same weight
applied. <br clear="none">
</div>
<div>Either you jostled something in the initial setup/study, or
your post spring work setup shifted something, throwing one
of the two data sets out as a valid data reference.</div>
<div>Either way,,,,this is possibly a mute point if it is now
all working for you as expected.� :-)</div>
