The RUST High Quality Carburetor is a vehicle component for any of the available modular vehicle engines. Facepunch added the modular vehicles in the Modular Vehicle Component Update on the 3rd of July, 2020.
Engine components, unlike modules themselves, may be added to a car in the field, or you can add them by having the vehicle raised on a powered Modular Car Lift.
All engines require a number of set components of assorted types for the vehicle to function.
Higher quality parts such as the high quality carburetor, High Quality Crankshaft, High Quality Pistons, High Quality Spark Plugs, and High Quality Valves greatly improve speed and performance over lesser quality models.
This component promotes better combustion, increasing the speed at which the engine can function. It also increases distance per Low Grade Fuel, meaning that you can travel further on less gas.
