Re: Mechanical Advance

Yipes!!

I ask one question and go away for two days...50 plus emails.

First of all you don't need a distributor machine to curve your
ignitions.  I bought a Dial-back-to-Zero timing light from Jacobs.  Most
everyone makes one now.  They are the most accurate device for checking
advance throught out the rpm range.  You can read the advance at any
rpm.  Some use a graduated dial and the newer ones are digital
readouts.  Distributor machines can and will have a certain amount of
play in them.  Electronics do not.  These are really great timing lights
and I highly reccommend them to all.
Thanks for all the responses.  I'm glad that unequal springs are all
right.  My TR-6 is currently set up with 12 degrees innitial and almost
another 28 degrees by 2500 rpm.  I'm getting slight spark knock in third
and even more in fourth if I get on it.  I think I'll go to a little
heavier spring on one side and see what happens.
Thanks again.
