YS Engine YSF2132 Carburetor Insulator DZ Insulator Gasket for Nitro Engines  [YSF2132]

Insulator Specifications

The YS Engine YSF2132 carburetor insulator is designed to sit between the carburetor and engine backplate on small-scale nitro engines, reducing heat transfer into the carburetor body. This insulation role helps to limit the impact of cylinder head heat on mixture stability, making tuning responses more repeatable in warm conditions.

Fitting the part is straightforward: clean and flatten mating surfaces, align the component so bolt holes match, and tighten mounting hardware evenly to avoid warping. Apply the engine manufacturer's recommended torque to screws and check the carburetor base for any signs of air leakage. Refrain from modifying or overtightening the insulator.

In practice, the insulator decreases sensitivity to heat-related vaporisation and idle fluctuation, supporting consistent carburation; it does not replace proper jetting but helps maintain a stable baseline for adjustments.
