I hope the following information is useful.
1. Locate top dead center on the compression stroke of cylinder one. (There should be a divot in the flywheel with what looks like a bb sitting in the center of it.) Line up the bb-mark with the pointer in the opening that lets you view the flywheel.
You can open the valve cover to watch the valves to make sure they are closed.
2. If you have a manual advance adjustment set it for 0.
3. Using a continuty checker (on a voltmeter) rotate distributor untill the points are just starting to open on the cylinder one spark wire.
4. Make sure that the wiring matches the correct firing sequence. Should be (1-5-3-6-2-4) moving clockwise.
5. This should be good enough to get it started. Once started you can use a timing light to get it dialed in.
I hope this is helpful. I am sure if I missed anything or anyone has anything to add they will chime in.
Good luck with your project.
