This is bad right??
I was looking over everything closely, to see if all vacuum lines and hoses were connected, and i was messing around with the spark plug wires because i was going to replace them today. Anyhow, I noticed that the rotor wasn't pointing towards the number one spark plug tower. Am I right? Which end of the rotor is supposed to be pointed towards the number one tower? Also how do I re-adjust this problem so my timing matches up? Can someone help?? Pics are available below......Thanks!

The rotor will be facing whatever terminal it was pointing at when you turned the car off. If you have #1 cylider at TDC then you have problems. Engines don't fire off #1 cylinder to start.

An engine doesn't stop on #1 fire position every time it shuts down. It will stop turning at any random point. You would need to bump the engine over till:
a) the timing pointer on the front harmonic balancer is at zero &
b) the valve train is in the right position for firing the plug...
Remember with a 4 stroke engine the piston comes to top dead center (TDC) twice, once to fire for the power stroke & once at the top of the exhaust & start of the intake stroke. Thats why you can have the timing mark at zero but the rotor is 180 degrees out firing the #6 cyl instead because the #1 is at the exhaust stroke.

The rotor spins inside the distributor cap. When you shut your engine off it can stop pointed at any point on the cap. The only time the rotor has to be pointed at number 1 is when you initially install the distributor. The rest of time it does not matter where it points.
