Carburetor Dellorto PHVA 17,5 TS
Carburetor Dell'Orto 17.5 mm PHVA TS for 50cc scooter, moped, motorcycle.
Larger carburetors increase cylinder filling and internal cooling is improved, resulting in higher performance and durability. Carburetor is a core part of your engine, so to increase the performance of your scooter, we recommend to change the carburetor as well as the exhaust to increase acceleration and top speed.
The main jet that comes with this carburetor is size 80. The carburetors are pre-tuned, usually fine tuning via the main jet is all that is needed. We recommend to order an additional jet (D. 6mm) to adjust the carburetor settings to perfectly match the setup.
This 17,5mm carburetor for automatic choke was developed especially for Minarelli (Yamaha Aerox, Malaguti F12, Aprilia SR and many more), but can also be installed on other models.
Attention: Carburetor is delivered without starter. You can use your original electric choke or order a starter with lever choke (e.g. the manual lever choke from Motoforce MF16.30001).

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
