Carb serial number

If I understand your question correctly, you're inquiring about the serial numbers (S/N) of the carburetors based on the engine's S/N.

If that's the case, here's the information:

• Constant Depression Carburetor Assembly 1/3 – Part Number (P/N): 892530, Serial Number (S/N): 19.2455
• Constant Depression Carburetor Assembly 2/4 – Part Number (P/N): 892535, Serial Number (S/N): 19.2479
