Seems like you are trying to do trouble shooting without any resources so have to be a little more creative. The engine is running now without a problem so it is not possible to troubleshoot. You are just guessing. The following is not a definitive for sure diagnostic, but if the following criteria are not met, you know where the problem is. Here is one think you can try. Is the fuel tank located above the carburetor? If so the fuel pump could be dead and the engine would still run because of gravity feed. If the fuel tank is below the carburetor, pull the fitting at carburetor and slip a hose on it making sure it will not leak, maybe need a clamp for this. Becareful with matching hose size. Use a rag or better use a container to capture any fuel, or use a rag under a container. There is the fire and explosion problem with gasoline. Turn on the ignition and see if there are several quarts of fuel pumped per minute into a container. This could vary with the exact model of Facet pump. Find the pump model number and I can look it up is you like If the carburetor is below the fuel tank, fuel will pour into the bilge if you loosen the fitting so you must turn the fuel off at the tank or disconnect the tank until you have the hose on the delivery pipe. You can also check any fittings before the filters to check for debris. If the filters are after the pump, check the fitting where the line goes into the pump.
Another thing to try is take the center wire from the distributor and place it half an inch from metal. Tie or tape down if needed, but make it half an inch. If there is no smell of gasoline around the engine, crank and see if you get a nice fat spark. Sometimes when an ignition is going bad, there is enough spart to start the engine, but it looks weak, jumps a quarter inch or less and is likely to quit any time. Be careful with the spark as these modern high energy systems can deliver enough amps to be lethal. Also, magnetos are very dangerous. My dad knew a fellow killed by a magneto. By the way, try the spark test first before opening any gasoline lines. Less chance of a fire
