Carburetion; General; Identification - Tecumseh VLV Technician's Handbook

General

Proper Carburetion Function is dependent on clean
fresh fuel and a well maintained air cleaner system.
Most causes of carburetion problems are directly
related to stale fuel and dirt ingestion. Inspection of the
carburetor for dirt wear and fuel deposits should always
be done before servicing the carburetor.
Carburetor Identification
Tecumseh carburetors are identified by a manufacturing
number and date code stamped on the carburetor as
shown. When servicing carburetors, use the engine
model number or the manufacturing number on the
carburetor to find repair parts in the Master Parts
Manual.
The engine has used both a split system and married
system carburetor. Below are the part breakdowns for
the two carburetors.
