That's not a part number. The number is stamped into the metal, not printed on the ceramic. You should be using NGK B6ES (7432) or Bosch W7CC (7998). With carbs, you should probably run one heat range hotter. The Cap'n

Yes, it's a Bosch plug. The equivalent NGK is B5ES, 6410. Chain stores only carry stuff they can easily sell in large volume.

I have 60 NOS Bosch W7C and 50 NOS Bosch W8C spark plugs. Most of them are in their original packaging of 10 plugs per box. I would be willing to open the boxes and sell them in groups of 4 plugs for $10.00 shipped.
