EU>My fellow Triumphers,

EU>I have the head off on my Spitfire and am having a go at indexing the spark
EU>plugs, (i.e. using spark plug washers as shims to aim the plug electrode at
EU>the intake valve). Having never done this before I've noticed that it can
EU>take 3 or 4 washers to get  the little suckers to aim properly. This is

EU>proper procedure or will the way the plugs are riding couteract any increase
EU>in performance I hope to gain?

EU>Great big thanks in advance,

EU>Eddy Ulm


Eddy,
 I fail to see the requisit for indexing spark plugs for normal use.
 Now, indexing the distributor I can understand because that is where
the spark comes from.
 I would be interested to hear the pros and cons on this thread.
Regards,
