Stripping And Rebuilding Vespa and Lambretta Carburetors
Having recently gone through this exercise myself, I’d like to compliment Oregon scooter rider Jeff Allen on what has to be the most thorough guides on carb strips for vintage scooters I’ve ever seen. Jeff also deserves praise for how beautifully and thoughtfully shot the video series is.
For Lambretta Series III models, Jeff strips and rebuilds a factory standard Dellorto SH/1 20mm carb though the principles are the same for all non-needle carburetors. The guide is presented in two parts:
For Vespa large frames, Jeff has put together a mighty five-part carburetor opus on the Dellorto 24/24 / 24/24e. Part one is presented here, links to the remaining four videos are then easily accessible:
If I have one small criticism it’s that Jeff leaves the rider hanging when it comes to correct choke, air mixture, and idle set up, but those black arts are thoroughly covered elsewhere on the ‘Internets’ and it seems that everyone has a different school of thought.
Perhaps we’ll see Jeff’s version online at some point in the future?
