Hi all,

I now understand "static" better, I always saw it but read it as vacuum
not hooked up.  

On my '72 with the vacuum hooked up (to the retard) I get 4 deg ATDC,
when I disconnect the vacuum I get about 10 deg BTDC.  Pretty much goes
along with what's been said

Steve

This subject is confusing to most folks, myself included. 10-12* BTDC
STATIC (engine still) timing will produce approx. 4* ATDC DYNAMIC
(engine running) timing at idle (less than 1000 rpm). This setting will
allow the engine to fire in almost any properly set up TR6. With
Richard's modifications the engine will accept more advance, but 30*-34*
TOTAL advance at 5600+ rpm should be the maximum to save your slugs from
a fate like Tim's #6 piston. This is where recurvung the distributor
comes in and is a whole other subject.
