FZ115S Regulator Spacer for RC Engines - YS Engine YSG2073  [YSG2073]

Spacer for FZ115S regulator mounting

This spacer is an RC-scale regulator accessory intended to position and secure a regulator unit on FZ115S-compatible setups. It serves as a precise mechanical interface between the regulator flange and the engine mount area, keeping alignment and spacing consistent during tuning and assembly.

The part is supplied as a single spacer element, not a complete regulator assembly. Its purpose is to correct clearance and alignment where the regulator body and mounting points require additional thickness to avoid contact with nearby components such as mounts, brackets, or cooling shrouds.

Installation is straightforward for experienced model technicians: remove the regulator mounting screws, insert the spacer between the regulator flange and the mounting surface, then refit the screws and verify alignment. Check that the regulator linkage and any fuel or vent tubing remain free and that the spacer does not impose torsion on mounting fasteners.

In tuning situations the spacer allows small positional adjustments to achieve reliable fuel flow and a stable mount under vibration. It suits glow engine setups where moving the regulator slightly improves access or clearance without altering the mount or regulator body.
