	No, you'll have to put the cap on and take a spark plug out and hold the outside to a good ground. If you don't, you'll get a good shock!

	Or. You can have someone else turn the key while your looking at the points. Two or three revolutions should tell you what you need to know.

	Leave the wires attached to the cap, leave the cap attached to the distributor....remove one wire at the spark plug end and hold the metal end of that wire about 1/8" from the block while cranking, with the ignition "on".. Hold the wire with something that is insulated or you may get the shock! If your plug wires have rubber cups on the spark plug end then remove a plug, re-attach the wire to the plug, and then hold the metal part of the plug against the block and watch for a spark at the electrode. You may have to do this inside or in the shade to see the spark... Rotor should rotate counter-clockwise..you can see this with the cap off, and you should see the points open a little....just .020 inch...

	Are you sure your gap is set correctly? And you double checked your wire routing and connections to ensure they are in the right spots? This video helped me when I was setting mine up and I know others here have used it as a valuable reference too. Don't give up yet!

	That video helps because it shows that the rotor should spin with the cap off. Mine is not spinning. what would cause the rotor to not spin? Also where does the braided ground wire on the fire wall connect to?

	The cam turns the oil pump through a gear arrangement, and the oil pump has a slot in the top of the shaft that receives a tab from the distributor shaft. Has your distributor been removed lately? Perhaps it did not get fully seated when it was re-installed. The first picture shows two distributor shafts with the tab. The second picture shows the slot in the top of the oil pump shaft.

	Yes a friend of mine who is a pretty good mechanic put it in. maybe he didn’t get set in all the way. SO either its not set in or the distributor is shot? only two reasons it wont spin?

	The distributor will only go in one way as that tab is offset to one side. Make sure it seats. It's easy for it not to and but appear to be OK. Shine a light down the hole to see where the slot is on the oil pump first if it helps.

	Or, the cam and oil pump gears are not meshing and the oil pump is not turning.... Even if it's shot/worn it ought to turn... Can you post pictures? I'm not sure what you mean by the braided ground wire....
