258 ignition timing...

Hummm, i am very confused now... I was reading my bible, or should i say my Chilton's, when something strange happened...Useally when i try to set my timing i use the plug wire which is the closest to the fire wall and i get a readying of around [email protected] and the engine seems to run well... So, while reading this nice book i suddenly though that i may be running 180 off since the beginning because they label n1 wire the one at the front of the engine (farthest away from the one i use!!!!)!!!
So, here is the question (please don't laugh!!!), how would i know that i am 180 off, the engine would run "nice" or not???, in the firing order n6 is not the last one so it would be strange to be 180 off??? Is it possible that my ignition is built with n6 being n1???
Well, i hope you understood me since i am not really sure i understand myself!!!!! [img]images/icons/smile.gif[/img]
Thanx for your answer....

Re: 258 ignition timing...

Oddly enough, what you've been doing is OK. The firing order is 1 5 3 6 2 4. Since the crankshaft turns two complete revolutions to fire all cylinders, it has completed exactly one revolution when number 6 fires, and the timing mark on the crank is back near TDC. It doesn't matter whether you use # 1 or #6.
