Rebuild Kit - 625 Street Demon

The Rebuild Kit - 625 Street Demon by Demon Carburetion is an essential maintenance component for street performance and bracket racing carburetor systems. Designed for serious enthusiasts and mechanics who demand precision fuel delivery, this rebuild kit restores your Street Demon carb to factory specifications and peak performance. Whether you're freshening up a high-mileage carbureted engine or preparing for competition, this kit ensures your fuel atomization and metering circuits function exactly as Demon engineered them.

This rebuild kit contains precision-engineered gaskets, seals, and internal components that eliminate fuel weeping, vacuum leaks, and lean-condition stumbles caused by worn carburetor internals. The kit addresses wear in the float bowl gasket, needle and seat assembly interfaces, and fuel inlet passages—critical areas where deterioration causes fuel pressure loss and disrupts the precise air-fuel ratios necessary for consistent idle quality and throttle response. Compact at just 0.35 lbs, the kit's contents are organized to guide you through a systematic teardown and reassembly, ensuring no passages are missed during the rebuild process.

Street and strip enthusiasts using 625 CFM Street Demon carburetors will benefit most from this rebuild kit, especially after 50,000+ miles of operation or when experiencing stumble off idle, flooding, or erratic idle speeds. Installation requires basic carburetor knowledge and hand tools—removing the carb from the intake manifold, soaking old gasket material, and carefully reassembling the float bowl, metering block, and choke housing with fresh seals. This kit is compatible exclusively with Demon Carburetion's 625 Street Demon platform, making it the precise choice for maintaining carburetor reliability on street, strip, and vintage performance applications.
