What did the 1st Harley Davidson use as a carburetor?

The first Harley-Davidson motorcycle, produced in 1903, used a simple carburetor design that was essentially a modified version of a common bicycle engine carburetor. It featured a single-cylinder engine and utilized a "float" type of carburetor to mix air and fuel for combustion. This early design laid the groundwork for the more sophisticated carburetors used in later Harley-Davidson models.
