YS Engine YSS1040 Regulator Body A 50ST Replacement for S1036  [YSS1040]

Regulator Body A 50ST - YSS1040 Replacement

This RC-scale regulator body is the YS Engine YSS1040 replacement for the S1036 regulator body, supplied as a direct-fit spare for regulator assemblies. It is intended to restore the original housing geometry and mounting points so internal regulator components remain correctly positioned during maintenance or setup.

Fit this part when the original regulator body shows signs of wear or damage, or when preparing an engine for bench tuning and routine service. The YSS1040 is a like-for-like replacement for S1036 style assemblies, and in most cases no modification to the regulator assembly is required once the part is properly aligned and secured.

Installation guidance: remove the regulator assembly from the engine following standard disassembly practices, note orientation and fastener locations, swap the old body for the YSS1040 unit, and reinstall using the same mounting hardware. Verify clearances and linkage alignment before running the engine at increased settings.
