Mr. B says:
"We consider the remade 22mm SH carburetors, made by Jetex or Spaco, to be such poor quality that we do not recommend them.
However, the trend is still to keep Lambrettas looking standard so we came across a modern rubber mounted Dellorto that can be used with the standard type Lambretta air boxes.
This manifold will let you fit a 25mm PHBL Dellorto, 24mm Mikuni carburetors onto a 200cc type cast cylinder (Factory, Rapido, Mugello or Original barrel).
It fits all MB/BGM RT cylinders - this is because they use the 200cc type inlet spacing.
It comes with a stainless steel long bolt to replace the long inlet stud, otherwise it is very hard to fit the manifold without dropping the engine.
One of many Inlet manifolds designed by us MB
It also fits the Mikuni and PWK type carbs."
