This set of reamers allows you to clean clogged carburetor jets and to enlarge the nozzle cross-section if you need a larger nozzle. This saves the sometimes not exactly cheap purchase of new carburetor nozzles in different sizes, if the exact size needed is not yet determined. The set consists of 8 reamers conical, pentagonal, sorted from 0.6 - 1.3mm and a reamer holder. In combination with the set of jet gauges an optimal tool to retune carburetors.AI-translation
