Modified blue carburetor clutch, compatible with 43cc, 47cc and 49cc engines 40mm and 44mm pull starters conversion parts for motorcycles, off-road vehicles and karts.

This product is a high-performance blue carburetor adapter plate kit from GOOFIT, specifically designed for small 43, 47, and 49 cc two-stroke engines. The kit includes a sleek blue adapter plate and all necessary mounting hardware for a secure and leak-free connection between 40 or 44 mm pull-start engines and standard small carburetors. It is the ideal solution for upgrading original plastic parts, fixing leaks, or optimizing the intake system of small engines. This kit is widely used on mini motocross bikes, go-karts, scooters, and general-purpose engines. 【Main Components and Functional Benefits】 Blue Carburetor Adapter Plate: Precise Fit: The adapter plate is precision-machined to fit the outlet of pull-starters with a 40 or 44 mm inner diameter, converting it into a universal interface for small carburetors (generally compatible with carburetors from Ø 14 to 19 mm). Performance Optimization: Optimized internal flow channels and a smooth surface effectively reduce intake turbulence, contributing to improved low-end response and increased throttle response. Aesthetic and Material Improvements: Manufactured from high-strength aluminum alloy with a blue anodized finish or high-strength composite materials, this clutch disc combines light weight, corrosion resistance, and a striking, modified design with significantly greater durability than the original plastic parts. The complete mounting kit includes special oil- and high-temperature-resistant gaskets that ensure a durable and reliable seal between the clutch disc, carburetor, and pull-starter. Special screws, clamps, and nuts ensure secure mounting and effectively resist the high-frequency vibrations typical of two-stroke engines. 【Specifications and Compatible Vehicle Models】 Compatible Engines: Air-cooled two-stroke engines with 43cc, 47cc, and 49cc displacements (commonly found in many domestic and European small cars). Compatible Recoil Starter Port: 40mm or 44mm diameter (please measure the inside diameter of the original recoil starter and carburetor port with calipers to confirm the size). Compatible Equipment: Mini motocross bikes, small racing karts, two-stroke motocross scooters, and common motorized equipment (lawn mowers, water pumps, etc.; available space must be checked).
