Complete carburetor kit for conversion to the Dellorto PHBL 25 carburetor.
Perfect replacement for all old MA or SH or for all tuning applications up to 250ccm. The original air filter box can be kept. To get the maximum performance you can use a so called remote filter system. The original intake hose is kept and supplemented by a Ramair filter.
The carburettor can be tuned much better. The engine runs over the entire speed range as if there was suddenly softener in the tank.
Thanks to the 180° throttle cable guide included in the delivery, the original throttle cable fits. You only have to change the inner cable.
All necessary tuning parts are included in the delivery.
We will gladly give you tips for a starting nozzle for your individual engine. Just send a mail to: lambretta[at]scooter-center.com.
This 
carburettor kit for the Lambretta engines with the small engine housing of the 125-190ccm class is ideal for all Lambretta riders who want or need to upgrade from the simple SH carburettor to the modern PHBL Dellorto. The throttle cable should be laid in large radii without kinks for a fluid function.
 With the practical nozzle sets and the needle set, engines from the original Li125 up to extremely open racing cylinders can be easily and uncomplicatedly vented.
