Andy:
The 4 ATDC number is only valid if you have a working vacuum
retard on your dizzy. I can't imagine that the Mallory will use a retard
(although it might have a vacuum ADVANCE). So, the correct number to use
is 10 BTDC. With a stock dizzy this will give 36 degrees total advance.
(There is 26 degrees of mechanical advance in a stock dizzy - at least
there is on my 1974-1/2)
I would set the initial timing to 10BTDC as a starting point.
You can try moving this around if your Mallory has more or less
mechanical advance than the stock dizzy.
Cheers,
Vance

Subject: Now that I have the Mallory - timing quesion
<snip>
I'll also be working with my LBC mechanic on the Mallory Unilite dizzy.
Drilling the shaft for the drive dog is beyond my scope of tools, and
getting help with timing always seems to be helpful. I'll surely show
my
ignorance when I ask the list for help with the timing settings. I
understand stock settings of 4 ATDC at idle. I don't understand the
"static" setting of 10 BTDC. I understand that the timing should
advance
as higher rpms are reached, but I don't what the proper advance should
be.
Should all these guidelines be thrown out with my set up described
below?
What should I be looking for with the new dizzy installed?
