The YS Engine YSE2132 insulator is manufactured to fit DZ170 CDI carburettors and provides a buffer between the carburettor and engine case to reduce heat soak and vibration transfer while running.
For fitting, ensure both mating faces are clean, place the insulator against the engine mounting flange, align the bolt holes, and tighten fasteners evenly to maintain a secure seal. After installation, verify idle and low-throttle behavior on a test stand before regular use.
During tuning and upkeep the insulator aids stable carburettor mounting and can help preserve steady idle and mixture under load, but it does not replace proper synchronization or routine fuel system inspections.
