These carbs have been supplied from Dell'Orto upon request from Casa Lambretta, for customers who want a larger carb kit for their Lambretta Lui 50 scooters fitted with a Casa 75cc conversion kit, using the standard manifold. These are supplied ready-jetted (as per suggested settings).

These carbs can be used in conjunction with the Casa Lambretta manufactired airfiilter B54a if you wish to maintain a standard look to your scooter (it is adviseable to open this out internally if used with a Casa 75cc kit).
