o.s plugs

i was looking at an os #8 plug, and noticed the copper washer missing. does os not supply a washer with its plugs? if not, is it needed?

That is a packaging error. The washer is needed for sealing as well as to keep the plug from extending too far into the combustion chamber.

Yup agree! if the washer is missing the correct compression int h

combustion chamber will not be reached and like the fella says you ru the risk of embedding the piston on to the plug! Ouch
