9 The spark plug gaf} is 01 conside rable impor1~e. as. if it is too lilrge or too small. the size of the spark ilnd its efficiency will be seriously impilired. The spilrk plug should be set to the ligure given in thl} Specifications ill the beginning of this Chapter; IOTa sel it, measure the gilp with a/cere, gauge. and then bend open. or close. the outer plug electrode untillhe correct gap is achieved. The centre electrode should never be benl as this may crack the insulation ilnd cause plug fAilure if nothing worse. 11 Relit the plugs, and re/ilthe leads from the distr ibu tor in the correct I"ing order. which is given in the Specifications. Screw the plugs in by hilnd initiilily then tighten them to the specified torque using the plug spilnnel.
