How to find the right part number for your small engine
Nine times out of ten, a part that doesn't fit was ordered from the mower's model number when it should have been ordered from the engine's. Here's where each number lives and which one matters for which part.
Three numbers, three jobs
The equipment model number is on a sticker on the deck or frame, for example Toro 20332 or Husqvarna YTH22V46. It decides the cables, blades and deck parts.
The engine model and type code is stamped into the metal shroud or valve cover, for example 122T02-0010 or GCV160 A1A. It decides the carburetor, air filter, oil filter and plug.
The part number on the old part is the final word. A carburetor has a stamp on its body or flange (C1Q-S68, WYA-44, 16100-Z0L-023). If that stamp matches a number in the "Replaces" list on our card, it fits.
Where to look on each machine
Push mowers: engine code on the shroud above the spark plug; deck model on a sticker at the rear of the deck.
Lawn tractors: engine code on the valve cover or a sticker on the blower housing; tractor model under the seat.
Trimmers, blowers and saws: model on the housing near the handle; the carb stamp is on the carburetor body, visible once the air filter cover is off.
Pressure washers and snow blowers: engine code on the shroud or a plate on the side of the crankcase.
When numbers disagree
Engines get swapped during repairs, so trust the stamp on the part itself over any manual. Carburetors that look alike can have different throttle linkages, so the carb stamp beats a photo match. Measure the mounting holes (centre to centre) and compare with the specs on the card. If you're still unsure, send us a photo at the counter.
