Description
A quality throttle base plate is foundational to carburetor performance—it’s the interface between your engine and fuel delivery. This Proform billet unit ensures consistent airflow metering and reliable secondary operation for 650-800 CFM carburetors, eliminating the weak point that can compromise throttle response and engine tuning stability. Built from CNC-machined billet aluminum and anodized for corrosion resistance, this is a direct replacement that restores or upgrades your carburetor’s core functionality.
