O.S. Engine OS73300712 7mm Dust Cap Set for T-1010, T-1020 (3 pcs)  [OS73300712]

7mm inlet dust caps for T-1010/T-1020

This O.S. Engine OS73300712 dust cap set is an RC accessory designed to shield the carburetor or air inlet on compatible glow engines. The package contains 3 pcs as shown in the product title and is intended for routine maintenance, bench setup, and protecting components between runs.

Compatibility is limited to the engine models listed in the product name, specifically T-1010 and T-1020; do not assume fit with other models or different shaft sizes. The stated 7mm measurement refers to the outlet diameter interface—confirm the mating part size on your engine before fitting.

Installation is simple for hobby-level maintenance: remove any existing cap or cover, slide the 7mm dust cap onto the outlet or fitting until it seats, and make sure it does not obstruct throttle or linkage movement. During bench tuning, these caps help keep debris out of the inlet so needle adjustments remain consistent and are less likely to be affected by contaminants.

Care is straightforward: wipe the caps with a dry cloth or use compressed air to remove grit prior to reuse, and inspect for cracks or tears before reinstalling. This item is described as an RC accessory and intended for model engine use only.
