I took my distributor off yesterday to replace the o ring, I made sure everything was still lined up when I took it off and I ran to the parts store, so I get back and the endlink on the dizzy has been spun. I tried to line it up and put the dizzy back on but all it does it turn over it wont crank, im guessing I need to adjust my ignition timing? and if so how do I do it? thanks

 

So you marked it before taking it off?

It is keyed one way, take it off and spin it 180 degrees and try again.

Also, did you remove the wires? if so check the firing order.

 

The distributer will only fit in one way, you cannot make a mistake with this.
What excatly do you mean when you say turn over and won't crank. Turning over is cranking.
Need more info please.
