YS Engine YSG7034 CAM DZ70 camshaft spare part  [YSG7034]

This YS Engine camshaft, model YSG7034, is a direct spare part intended for DZ70-series RC glow engines. It serves as the replacement cam component that governs valve timing and helps retain designed engine timing characteristics during service and rebuilds.

Use this camshaft when replacing worn or damaged timing components, or when restoring factory timing after disassembly. The part is presented as an RC-scale spare for routine maintenance and tuning tasks; no modifications or extra tools are assumed beyond standard engine service practice.

Installation notes: confirm cam orientation and timing marks during reassembly, verify clearances and proper endplay per your engine's service procedure, and run a controlled break-in or check run after installation to confirm smooth operation.
