7mm Dust Caps (3 pcs) O.S. Engine OS73300712 - T-1010 T-1020  [OS73300712]

Dust caps, 7mm size, for T-1010/T-1020 engines

The O.S. Engine OS73300712 dust cap set is an RC-scale accessory made to protect the carburetor and air inlet area on compatible glow engines. The set includes three items, consistent with the product title, and is useful during bench setup and storage between sessions.

Only the models listed in the product name—T-1010 and T-1020—are guaranteed for fit; do not presume compatibility with other engines or shaft sizes. The 7mm measurement represents the nominal outlet size for mating parts, so confirm dimensions before installing.

To install: take off any existing cap, push the 7mm dust cap onto the outlet or fitting until it sits securely, and verify there is no interference with throttle or linkage travel. These caps are especially handy when tuning on the bench because they help prevent debris from entering the inlet which could skew needle settings.

Cleaning and care are minimal: wipe with a clean cloth or use compressed air, inspect for splits before reuse, and store in a dry place to avoid dirt buildup. This product is sold as an RC accessory for model engine use only.
