Assuming all your other ducks are in a row, (Spark advance, gas turned on, Ign. Key on) Let's make sure you're plugs are getting current before we start replacing anything. First, clean the points, then with them open and the key on, see if there's any current getting to them. You can use a clip lead the movable arm of the points and "spark" it against rigid base. It should spark. If it doesn't, that can be a bad pig tail in the distributor (Pigtail is the term commonly used for a short little wire) It may be shorted, it's not uncommon. It would probably help if you have a Ohmmeter. We use them quite a bit for checking continuity of circuits. Let us know how your doing! About the gas. As you probably know, Mod A s have no fuel pumps and are a gravity feed system. Sounds a little primitive I know. But it works fine, even on hills. The problems are usually rust in the tank, which clogs the whole system. The best thing is too drain every bit of gas out and put a gallon of fresh gas into the system. Again get back too us when that's complete and still not starting.
