Re: [6pack] Rule of 13??

["Mark J. Bradakis" <mark@bradakis.com>]

I usually adjust valves in firing order sequence.  When one cylinder has 
the intake
and exhaust valves 'on the rock' with one just closing and the other 
just opening
you adjust the valves on the partner cylinder.  On the TR6 the partner 
cylinders
are 1- 6, 2 - 5, 3 - 4  Just go along and do them 1 - 5 - 3 - 6 - 2 - 4

If you have a cam where one valve or the other is open at the top of the
compression stroke, this won't work - and chances are neither will your 
motor ;-)
