Jet, main (
A clogged or worn main jet starves your Toro mower's engine of fuel at full throttle, causing sluggish acceleration and poor cutting power. The main jet precisely meters fuel flow into the combustion chamber—when it fails, you'll notice hesitation, stalling, or rough idle even after cleaning. Genuine OEM Toro main jets restore exact fuel atomization and engine response.
At Repair Clinic, we stock genuine Toro lawn mower carburetor parts that match your mower's original specifications. Replace your main jet to regain smooth throttle response and reliable starting.
A restricted or undersized main jet limits fuel delivery when you increase throttle. Debris, varnish, or a permanently clogged orifice prevents the engine from drawing enough fuel. Replace the main jet with a genuine OEM part matched to your engine displacement and fuel type for full power restoration.
Light carbon deposits may respond to carburetor cleaner and a fine wire probe, but heavy corrosion, ethanol damage, or internal pitting means replacement is safer. OEM main jets are inexpensive insurance against recurring clogs and fuel metering errors that cleaning cannot fully resolve.
Locate the yellow model label on your Toro mower's chassis, typically under the seat or on the frame side. Write down the full model and serial number, then enter it into Repair Clinic's search tool to identify the exact carburetor assembly and main jet specification for your engine.
Toro main jets typically range from #60 to #80 depending on engine cc and altitude. Never guess or substitute jets from other brands—undersized jets starve the engine; oversized jets flood the carb and foul plugs. Always match the OEM jet size stamped on your carburetor or listed in your Toro service manual.

Toro prints the model number on a label or plate attached to the mower chassis, often under the seat, on the frame near the blade deck, or on the engine housing.

Enter the model number in our model number lookup, and the catalog narrows to parts made for your unit across every mower system. This step helps match the full range of associated parts to your specific Toro mower instead of relying on appearance or a partial number. You order with confidence knowing the fit is right.
