Carb Insert 2in Tall 1.400in Diameter

The Carb Insert 2in Tall 1.400in Diameter is a precision carburetor spacer engineered for serious engine builders and performance enthusiasts seeking optimized air-fuel mixing and improved throttle response. This component functions as a critical transition element between your carburetor and intake manifold, directing atomized fuel and air charge more efficiently into the combustion chamber. Whether you're tuning a street-strip vehicle, bracket racer, or classic hot rod, this insert addresses the fundamental challenge of carburetor-to-manifold compatibility while enhancing cold-start performance and mid-range drivability.

Manufactured to exact tolerances, the Carb Insert 2in Tall 1.400in Diameter features a precisely machined 1.400-inch bore diameter and 2-inch height that ensures proper fuel atomization without creating restrictive pressure losses. The two-inch vertical spacing allows carburetor selection flexibility while maintaining optimal plenum volume geometry—critical for consistent air velocity across all intake runners. Weighing just 0.85 pounds, this insert minimizes rotating and reciprocating mass while its compact footprint (6.1 x 2.25 x 7.9 inches) fits standard engine bay configurations without requiring extensive bracket fabrication or manifold modifications.

Mechanics and engine builders specify this carburetor insert when addressing rich-running conditions, fuel puddle formation during light throttle transitions, or when switching between carburetors of different flange designs. It's particularly effective on small-displacement engines or forced-induction applications where precise fuel distribution prevents flooding and vapor lock issues. Installation requires only standard fasteners and basic hand tools; the insert mounts directly between your existing carburetor and intake manifold gasket surfaces, making it an ideal upgrade for stock-to-modified engine conversions and carburetor swaps where factory spacing doesn't match your chosen induction setup.
