Toro 133-1532 Carburetor Insulator

Product Description

The TORO 133-1532 is a carburetor insulator designed to fit between the carburetor and the engine intake on small-engine outdoor power equipment. This component acts as a thermal and vibration buffer, reducing heat transfer from the engine block to the carburetor body and helping maintain consistent fuel delivery. It is a direct OEM-style replacement part serviced by licensed small-engine technicians and qualified equipment repair shops. Proper carburetor insulator condition is essential for reliable engine starting and smooth operation across the load range typical of turf maintenance equipment.

This insulator is a Toro-sourced replacement part intended for lawn and garden power equipment applications. It is suited for small gasoline engines commonly found in walk-behind mowers, trimmers, and related turf equipment. Installation is appropriate during carburetor rebuilds, fuel system service, or any repair where the existing insulator shows cracking, warping, or deterioration from heat cycling.

Key Features

• OEM Toro replacement part ensuring proper dimensional fit and material compatibility
• Acts as a thermal barrier between the engine block and carburetor to reduce vapor lock risk
