Carburetor, early model service kit
This kit includes all the most current jets, nozzles and gaskets necessary for a bringing your carburetor up to the latest factory configuration. If you have an older 4 bolt carburetor, or you’re simply not certain whether or not you currently have the correct jets and nozzles, this kit is your best choice.
This kit contains the same parts as the late model kit (appropriately sized for early model carburetors) except for the main discharge nozzle which is no longer available for early model carburetors. The kit also contains an adjustable main jet which was standard on early model carburetors.
