Walbro Carb Identification: A Comprehensive Guide

Walbro carburetors, commonly found on chainsaws, trimmers, and other small equipment, feature distinct markings that indicate their model and series. This guide will walk you through the key identifiers and their locations on your Walbro carb.

Where to Find the Identification Numbers

The most important identifiers are typically stamped or printed on the carburetor body itself. Look for these in a few key areas:

• Main Body: Often located on the side of the carburetor, near the fuel inlet or choke lever. This is the primary location for the model number.
• Metering Cover: Sometimes, the model number is stamped on the metering cover, which is the side opposite the fuel pump.

• Date Codes: Some carburetors have date codes indicating when they were manufactured.
• Batch Numbers: These can identify specific production runs.
• Dealer-Specific Markings: In some cases, manufacturers may add markings to carburetors supplied to specific equipment manufacturers.
