Your way and my way are different, Bob. I'd be finding an old carburetor with the same venturi diameter as the original, that had a convenient flange for mounting, sat well on the engine, was easy to connect controls to, and came with a good air cleaner that would also fit well on the engine. Then I'd repeatedly solder and drill-out the main jet and the emulsifier side-holes until it ran properly. However, we each have our own interests and pleasures. Paying $100 for the wrong carburetor does not even fit on my long list of preferences, let alone my short list.
