Tapping on the side of the carb might or might not have been related to the engine starting back up. I think to know if it is related, I need at least one more example of that solving the problem. The entire fuel system is new from a new gas tank, fuel lines, fuel pump, fuel filter and rebuilt carburetor. I will check the bowl as suggested to see if any fuel squirts. I will also try a spark test, but I should also point out all new wires, points, plugs, coil, cap and condenser.
