YS Engine YSF2132 Carburetor Insulator DZ Thermal Isolation for RC Nitro Engines  [YSF2132]

Thermal Insulator Overview

This YS Engine YSF2132 carburetor insulator sits between a nitro engine carburetor and the engine backplate to limit heat soak and maintain mixture stability during operation. It acts as an insulator gasket to reduce heat transfer from the cylinder head into the carburetor body, helping make tuning more predictable when temperatures rise.

Fitting is simple for hobbyists: clean mating faces so they are flat, place the insulator aligning all bolt holes, and tighten the mounting screws evenly to avoid distortion. Use the engine maker's recommended torque on mounting hardware and confirm there are no air leaks at the carburetor base after installation. Avoid overtightening or modifying the part.

In practical tuning this insulator helps lower sensitivity to heat-induced vaporisation and idle drift, giving a steadier baseline for needle adjustments without by itself changing required jet sizes.
