Regulator Spacer for FZ115S - YS Engine YSG2073  [YSG2073]

FZ115S regulator spacer overview

This accessory is designed for RC-scale regulator mounting on setups compatible with the FZ115S. It provides a reliable spacer between the regulator flange and the engine mounting surface to maintain correct alignment during tuning and operation.

The unit is sold as a lone spacer element rather than a full regulator kit. Its job is to remedy clearance issues where the regulator body and mount points need a small increase in thickness to prevent contact with surrounding parts like brackets, mounts, or cooling shrouds.

Fitting is simple for those familiar with model engine work: remove the regulator fasteners, place the spacer against the mounting face, then replace the screws and check alignment. Ensure linkages and any fuel or vent hoses are not pinched and that the spacer does not stress the fasteners.

During tuning the spacer helps fine-tune regulator placement for steady fuel flow and secure mounting under vibration. It is suitable for glow engine setups where minor positional changes of the regulator improve access or clearance without modifying the regulator body or mounting hardware.
