This BRC carburettor conversion kit is intended to convert a 2017-2018 Husqvarna TE 250 or TE 300 donor engine to a 510 cc two-stroke configuration for carburetted applications. It is not a complete engine; it is a conversion kit that must be assembled using parts from the listed donor engine, reusing assemblies such as the transmission, clutch assembly, kickstarter assembly, water pump, intake, ignition and covers where possible. The kit is supplied for engine conversion work rather than as a ready-to-run engine assembly.
