Ossa timing
« on: September 29, 2012, 07:29:31 pm »
my 73 explorers ignition had a dummyspit at CD9,put a spare on,but have run out of slot adjustment on stator plate at 2.2mm before TDC,clymer manual gives ignition timing @ 2.75- 3 for 71-72 models,(i'm assuming 73 model would be the same),both are 5 wire stators/humongus rotors,the timing location pinholes is left of centre on the replacement stator,my original is dead centre on the "trigger" plate,(both rotors are centrally indexed??),WTF??,anyone come across this "problem",i realize i could extend the slots,but not too a desirable fix as plate has wider stepped sections after narrow slots,cheers mick
work,the curse of the racing class!!
if a hammer dosn't fix it,you have a electrical problem!!

You should be using a cigarette paper and a pencil!!! I was hoping you got it sorted!
