device of carburetor on an internal combustion engine, particularly motorcycles.

摘要

The carburetor of a motorcycle engine is fastened to an engine cylinder by a thin resilient hose connecting the fuel mixture outlet port of the carburetor to the intake port of the cylinder. The carburetor is fastened to the casing of the associated air cleaner much more rigidly than it is fastened to the cylinder. The fastening connection between the carburetor and the air cleaner casing is provided by a tubular member having a wider orifice fastened to said casing, a narrower orifice fastened to the carburetor, and a shoulder portion connecting the orifices and of greater wall thickness near the float chamber in the carburetor than elsewhere.
