Overview
The HPI Racing Dust Protection and O-Ring Complete Set has the o-rings needed to reseal a Nitro Star S-25 engine: rear cover, carburetor and main needle o-rings. It's also a standard part on the Nitro Star F3.5 V2 pullstart engine.
Worn o-rings let in air and dirt, which makes the engine hard to tune and wears it out faster. A fresh set brings back a proper seal.
