Genuine OEM Replacement Part
Prevent fuel boiling, rough idling, and engine vapor lock issues with this genuine OEM Carburettor Insulator Block. Specifically engineered for the fuel intake tract on the Titan Pro TP690 Walk-Behind Field Topper Mower engine, this spacer sits directly between the cylinder head and the carburetor assembly. Its vital function is to act as a thermal barrier, blocking high engine combustion heat from transferring directly into the metal carburetor body.
Titan Pro Tech Tip: Check for Hairline Cracks!
Because this insulator block is made of hard plastic and is subjected to constant heating and cooling cycles, it can eventually become brittle. If your engine is "hunting" (revving up and down wildly at idle) or running too lean, inspect this plastic spacer closely. Over-tightening the carburetor mounting nuts often causes hairline cracks around the bolt holes, pulling unmetered air into the intake tract. When replacing it, always use fresh gaskets on both sides to maintain an absolute airtight vacuum seal!
Molded from a high-grade, heat-resistant black polymer composite, this structural insulator retains a perfectly flat mating profile to ensure reliable fuel atomization and consistent performance under heavy clearing loads.
