N18s were used across the board for all models in 56. When I asked for set of plugs for my 56 back in the late 1980s, I was given a set of N16YCs. So, you should be OK there.

After starting the engine, do you have to keep feeding fuel, manually, into the carb to keep the engine running?

If so, then you may have a fuel supply problem. Check fuel pump output. However, before you go cranking the engine with the fuel line emoved from the carb, I strongly recommend that you disconnect the PRIMARY wire from the coil to the distributor.

If not, then you may have a weak accelerator pump in the carburetor. With the engine NOT running, hold the carb's choke valve open, look down the bores, and give the throttle shaft a twist. You should see a healthy squirt of fuel; if not, then it's time to rebuild.
