The width of the electrode has no effect on the spark timing as the spark occurs at the moment the points open.The rotor electrode needs to be adjacent to the distributor body electrode when the points open. Hope this helps Regards, Steve : I know this question has been asked before but how do you : set the timing on an "A".It is usually said that when the : pin goes into the indent in the timing gear the rotor : should be pointing at electrode for #1.Which part of the : rotor since it is several times wider than electrode? What if : the indent on timing gear is so shallow that your not sure : if youve found the spot (as mine is)? It seems to me I heard : somewhere of using a test lamp at the points after this.How : is this done? : Thanx in advance.....Jack |
