Carburetion; Identification; Parts Breakdown - Tecumseh VLV Technician's Handbook

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 parts breakdowns for
the two carburetor's.
