Get a power drill and spin the gear clockwise until you've got oil coming out of the hose. If you do, you're fine. If not, there may be an issue with your pump or not enough oil perhaps?
Noy a good way to do that, the oil pump pumps by spinning counter clockwise and you have to drop the pump and put it back in is use the method. Better to pull the spark plugs and spin the motor with the starter using a remoter starter switch. If your "in and out" hoses are correct might take a couple of minutes, assuming that you primed the OP.
Plug the vacuum port on the carb and do not hook up the vacuum adv unit, leave it alone, if you remove it the adv plate can move and screw up you timing, 12* BTDC at idle and 34-36* BTDC at 2,800. Make sure that you mech adv system is healthy and not sticky.
