This dust cap set is an accessory for O.S. glow engines designed to shield the carburetor intake from dust and grit. It acts as a simple barrier when the model is stored, moved, or awaiting maintenance, with an emphasis on secure fit and long service life rather than changing engine performance.
Compatibility is limited to the models listed in the product name, so confirm your engine code before fitting. Installation is simple: hand-seat the cap over the carburetor intake until it sits snug, and avoid forcing the cap onto a mismatched opening to prevent damage to the carburetor body or the cap itself.
The caps are intended as a maintenance and storage aid for hobby use and do not alter engine tuning or internal settings. Keep the caps clean and inspect them for wear prior to reuse to preserve a reliable seal.
