I Noticed the grease cup on the distributor is interfering with the vacuum advance mechanism. Is this normal?
I believe you can reposition the distributor to move the grease cup away from the vacuum advance. You may have to move the gear mating to the crankshaft by a tooth, making sure that you get the oil pump engaged as well. Your spark plug wires may have to be moved by one position on the cap.
On the vacuum reservoir, a good idea is to put a check valve between the vacuum source and the tank and the rear axle (or whatever is using the vacuum). That keeps the vacuum reservoir fully charged and available even if the engine isn't running.
