O.S. Engine OS73300712 dust cap set 7mm T-1010,T-1020 (3 pcs)  [OS73300712]

7mm dust cap set for T-1010/T-1020

This O.S. Engine OS73300712 dust cap set is an RC-scale accessory designed to help protect the carburetor/air inlet area on compatible glow engines. The package contains three pcs, matching the product title and intended for routine maintenance, bench setup, and protecting components between runs.

Compatibility is restricted to the models listed in the product name, specifically T-1010 and T-1020; do not assume fit with other models or shaft sizes. The nominal 7mm dimension indicates the intended outlet diameter interface, so confirm the mating part size on your engine before installation.

Installation is straightforward for hobby-level maintenance: remove the existing cap or cover, slide the 7mm dust cap onto the outlet or fitting until it seats, and verify it does not interfere with throttle or linkage travel. As a tuning accessory, dust caps keep debris out during idle adjustments and bench tuning sessions, which helps maintain consistent engine response and reduces blown-in contaminants that can affect needle settings.

Care and upkeep are minimal; wipe clean with a dry cloth or use compressed air to remove grit before reuse, and inspect for cracks before reinstalling. This product is described and sold as an RC accessory and is intended for model engine use only.
