This replace the original carb on my 1966 SX 200. Perfect fit, works brilliantly. Thanks for the prejetting! Cheers

only is it a great carburettor kit for my restored Lambretta, but, when the original was accidently mis-addressed, the replacement arrived within a day. Fantastic service.

Tim L on 21 Jul 2019 asked "Hi, I've got a 1981 serveta jet 200 with stage 4 tune/dellorto SH2 22mm carb and considering upgrading to this newer 25 (when in stock). The air filter is on the side of the toolbox and reasonably new, so can I connect this ok? Touring and reliability over performance! Thanks and regards Tim"

MB Scooters Ltd replied: Ive not tried one but it should fit

Andrew M on 30 Jan 2019 asked "If I already have a standard 22mm Jetex Carb do I actually need to upgrade the inlet manifold, air filter and connector hose etc. for the 25mm? Or would the standalone 25mm carb not simply swap in as is? If I went for 28mm I presume the full kit would be required? Andrew."

MB Scooters Ltd replied: The Jetex manifold doesnt fit the carb. The only thing you can reuse is the air bellows

Peter c on 21 Sep 2016 asked "I had the engine upgraded on my lambretta 150 li to a 198 mogulo and a Delors phish 30 was fitted could this be changed to a Delors 25 so as I could then keep my air box"

MB Scooters Ltd replied: Yes should be a straight swap

Renaud on 20 Jan 2015 asked "Hi I am planning a racetour 190 conversion on a small block with mb clubman + tv gears This will be for town/touring. Therefore i hesitate between 25mm an 28 mm carbs. What would you advise? Regards Regards"

MB Scooters Ltd replied: If you do not want the best acceleration and top end speed as it is for town/city use then use the 25mm
