The springs are probably ok. Using two different springs is common to attain
the desired curve or to stop bouncing at high rpm. Put it back in and with a
timing light, check the advance against the book. Using an adjustable
advance timing light helps but is not necessary. Don't forget to plug the
vacuum line for the test. Chilton's book has three timing readings at three
rpms to check your curve by for the year car you have.

I have just finished cleaning up my distributor because the mechanical
advance
wasn't working. I found two problems. First: the connection between the
shaft
and the cam was so corroded that movement was not possible. Second: this
may
have been exacerbated (my $10.00 word for the day) by the previous owner.
It
seems as though I have two different mechanical advance springs in my
distributor. One looks like a coil spring off the front suspension of a
Chevy,
the other looks like a spring from a watch. This can't be right can it? My
guess is the mechanical advance never worked and froze on the shaft.
Well now everything is cleaned up and moves freely, but I don't know where
to
get replacement springs, any suggestions?
