As an authorized Multiquip parts source, DHS Equipment supplies this part direct — so you get the exact component engineered for your machine, not a guess.

Key Features
- Genuine OEM Heat Barrier — Manufactured to Multiquip's original specification, this insulator provides the correct thermal isolation between the carburetor and intake manifold that the engine was designed around.
- Drop-In Carburetor Mounting Fit — Matches the original bolt pattern and gasket interface, so installation is straightforward with no trimming or adapting needed.
- Confirmed Fitment — Verified for JWN24HTCSL Whiteman ride-on power trowels and AR14H rollers.
- Protects Fuel System Consistency — By blocking heat transfer from the engine into the carburetor body, this insulator helps maintain stable fuel delivery and prevents heat-soak issues that can cause hard starts and rough running.
- Fuel System Safety Integrity — A cracked or missing carburetor insulator can allow excess heat near the fuel circuit; replacing it with the correct OEM part restores the intended thermal barrier and supports safe engine operation.
The carburetor insulator sits between the carburetor and the engine's intake manifold, acting as a thermal barrier that prevents engine heat from transferring into the carburetor. This heat isolation is critical because excess heat in the carburetor body can cause fuel to vaporize prematurely — a condition known as heat soak — which leads to hard starts, rough idling, and inconsistent throttle response. When the insulator cracks, warps, or deteriorates, the carburetor is no longer protected from that heat, and engine performance suffers quickly.
