carburetor YSN PHBL 25mm AM, SD, BT with lever choke

The 25mm PHBL tuning carburettor is ideal for automatic scooters and Vespa classic gear shift scooters. For automatic scooters, it is mostly used on 2-stroke maxi scooters. However, this carburettor can also be used on 50cc engines with appropriate modification for high-end tuning. On gear shift scooters, this carburettor is usually installed on a small-frame vehicle that retains the original air filter box. An easy-to-tune carburettor that is in no way inferior to the identical Dellorto carburettor.
