In reality, the thing can be pointing at #5, so long as #1 is in the #5 position on the cap.
Know what I'm saying???
You've also not given us enough information on the motor. Alky/gas? Compression? Spark Plug Gap? N/A? Nitrous? Blower/Turbo? What ignition system? Mechanical Advance? Vacuum advance?

Whats the rotor look like? Is the tip eaten away at all? What about the posts on the inside of the cap? Do they have any grooves in them? Is the spring on the rotor making good contact with the center post on the cap?
It sounds to me like spark is either being cross fired from carbon tracking, or it's not jumping the gap at all due to weak spark.
So, it could be...
Weak Coil
6AL box is firing
Carbon inside the cap
Rotor to cap connection isn't sufficient.
Just speculation though.

I have mine locked out and I never have to touch the timing once the distributor is in, although I do check it with a light. I put the balancer at exactly 38 deg btdc and put the distributor in with the rotor pointed exactly at the #! plug post...If I need to I turn the oil pump with a screwdriver. It has always been on the money when I start it and put a light on it. This only works with the advance locked out.
