Mega ZX21 Rubber Carb Bellows
MEG202089
Flexible rubber carb bellows (MEG202089) for Mega ZX21 DSII+ nitro engines, providing dust-proof sealing and smooth throttle linkage movement between carburetor and crankcase in 3.5cc RC racing applications.
Protect your Mega ZX21 DSII+ nitro engine’s carburetor throat with the genuine rubber bellows (MEG202086), engineered for Serpent 3.5cc power plants in high-dust 1/8-scale off-road environments. This durable, accordion-style boot seals the gap between carb body and crankcase while allowing full-range throttle barrel movement without binding or air leaks. Molded from fuel- and heat-resistant rubber, it blocks dirt, sand, and moisture from entering the intake tract—preventing abrasive wear on internal components and maintaining consistent venturi vacuum. Easy to install during routine maintenance or rebuilds, this factory replacement restores clean airflow, crisp response, and engine longevity.
