Use a gas can and length of fuel line. Disconnect fuel from tank at filter, Connect gas can line to filter
Prefill filter
Edit, remove filter and dump contents into clear container

My next guess would normally be the distributor pick up coil, but hard to believe it would suddenly go bad while layed up.
So' I'm more leaning toward a wiring issue where some corrosion developed
Here is a TB V troubleshooting flowchart

I had a terminal end corrode away inside the connector of wires coming from pick/up to ignition module. Difficult to see but no spark.
