DZ70 Camshaft Replacement YSG7034 for DZ70 Engines by YS Engine  [YSG7034]

This YS Engine camshaft, model YSG7034, is a direct spare part intended for DZ70-series RC glow engines. It replaces the cam component that controls valve timing and helps preserve the engine's original timing profile during servicing and rebuilds.

Fit this camshaft when worn or damaged timing parts are found, or when restoring factory timing after engine disassembly. The item is supplied as an RC-scale spare for routine maintenance and minor tuning tasks; no special modifications are expected beyond standard engine service procedures.

Installation notes: confirm cam orientation and timing marks during reassembly, check clearances and endplay according to your engine's service manual, and perform a controlled run-in or verification run after installation to ensure correct operation.
