First make sure you are on the compression stroke. Remember you have
two times when the #1 cylinder is at the top of the stroke. When it
is on compression the rotor should point to the #1 cylinder. You may
have lined up the marks on the exhaust stroke.
The drive dog on the dizzy is eccentric not concentric. If you look
closely it is slightly off center and can only be installed in the
engine one way. The dog can however be installed on the dizzy 180
degrees off. On my spare, which I have no idea if it is correct, when
I turn the distributor upside down and point the rotor toward me the
dog is slightly to the right of center. To turn the dog 180 degrees
just knock the round pin out and rotate the dog and reinstall the pin.
Before you do this make sure this is the problem.

Yes, changing the plug order will work (if you are off 180 degrees),
but you still have to fire 1342. You need to "rotate" the wire
position on the dizzy cap 180 degrees. Number one will be in the 7
o'clock position, not the 2 o'clock position.
