I answered Bill Pugh's question about the rule of 13 when adjusting the
valve rocker clearance on the TR6 engine. That was on the Six Pack list.
Here it is again for the rest of you.
There was a great article in TRA on adjusting valve clearance, I now
clearly understand the "Rule of 8", and finally figured out how to
use my "ClickAdjust" tool, Casper's valves have never been happier ...
So my question is, is there a "Rule of 13" for the TR6, Rosey is
jealous and would like to have the same attention that Casper got
... ;-)
Thanks folks ...

Hi Bill,
What a coincidence, I just finished adjusting the valves on my 73 TR6. The
rule of 13 means that when valve 1 is fully open, you adjust number 12.
Take the number of the valve you want to set, subtract it from 13, then be
sure the corresponding valve is fully open. To save time here is the order
in which the valves open. . . .
FULLY OPEN ............ADJUST
1 . . . . . . . . . . .12
7 . . . . . . . . . . .6
9 . . . . . . . . . . .4
2 . . . . . . . . . . .11
5 . . . . . . . . . . .8
10 . . . . . . . . . .3
12 . . . . . . . . . .1
6 . . . . . . . . . . .7
4 . . . . . . . . . . .9
11. . . . . . . . . . .2
8 . . . . . . . . . . .5
3 . . . . . . . . . . .10
Of course this meant I had to refinish the valve cover. That made the air
cleaner look bad so it got bead blasted and repainted too.
