Carburetor Dellorto PHBN LS 17,5
Carburetor Dell'Orto 17.5 mm PHBN LS for 50cc scooters, mopeds and motorcycles.
Larger carburetors increase cylinder filling and improve internal cooling, resulting in higher performance and durability. The carburetor is a core part of your engine, to increase the performance of your scooter, we recommend replacing the carburetor and exhaust to increase acceleration and top speed.
The main jet supplied with this carburetor is size 90. The carburetors are pre-adjusted, fine adjustment via the main jet is usually sufficient. We recommend ordering an additional jet or a jet kit (D. 6mm) to be able to adjust the carburetor settings perfectly to the setup.
This 17.5 mm carburetor with manual choke was specifically designed for Minarelli engines (such as the YAMAHA Aerox), but it can also be easily installed on other scooters, mopeds or motorcycles as a replacement for the stock carburetor.

Carburetor for scooters, motorcycles and mopeds
The smooth operation and optimum power output of your scooter, motorcycle or moped depends, among other things, on the carburetor, whose job is to create the right mixture of air and gasoline.
How the carburetor works
When the rider operates the throttle, the carburetor slide moves upwards, increasing the air flow that is sucked in through the air filter. The carburetor then mixes this air with petrol, creating a combustible mixture. This mixture is fed into the cylinder through the intake manifold and the reed valve.
The carburetor is equipped with jets to adjust the ratio of fuel and air and thus ensure an optimum air-fuel ratio. It is important that you adjust the carburetor settings to the setup of your engine.
Adjusting the Carburetor
Proper carburetor adjustment is critical for optimal engine operation and durability. Depending on the type of air filter, cylinder and exhaust of your setup, you will need to readjust main and pilot jets. To check the correct operation of the carburetor, you can refer to the color of the spark plug:
- White spark plug = too lean
- Black spark plug = too rich
- Brown spark plug = optimal setting
