Zenoah K330481150 Carburetor Diaphragm Replacement Part  [K330481150]

Overview: Carburetor Diaphragm for Zenoah Engines

This is an RC replacement diaphragm provided without packing, intended as a service part among Zenoah engine spare parts. The diaphragm functions as the consumable membrane within diaphragm carburettors and is used during scheduled maintenance or when replacing ageing components.

To install: remove the carburettor cover, confirm or transfer the correct gasket if available, position the diaphragm flush with the mating surface, then reassemble and test for airtight operation. As this item ships without packing, save the original gasket or purchase the appropriate packing before completing assembly.

For tuning and fault-finding, a bad diaphragm can cause erratic idle and inconsistent throttle response. Replacing it is a typical first measure to regain steady fuel metering; once fitted, verify idle settings and needle adjustments while the engine runs safely on a bench.
