Multiquip 16211Z4V000 Insulator Carburetor - OEM Replacement Part

The carburetor insulator creates a heat-resistant seal between the carburetor and engine block on concrete saws, preventing air leaks that cause rough idling, poor acceleration, and fuel delivery issues. This thermal barrier protects the carburetor from excessive engine heat while maintaining proper air-fuel mixture ratios critical for Honda GX200UT2QXC9 gasoline engine performance.

On the SP1G concrete saw, a deteriorated carburetor insulator manifests as difficulty starting, erratic engine speed under load, or fuel seepage around the carburetor mounting area. This gasket component is subject to heat cycling and chemical degradation from fuel vapors, making it a common maintenance replacement item during carburetor service or when addressing fuel system problems. The insulator must form an airtight seal to prevent unmetered air from entering the intake system, which would lean out the fuel mixture and cause poor cutting performance or engine damage.

Compatible with the following Multiquip models:

• SP1G Concrete Saw
