The upright Peugeot engines have a very restricted manifold - when fitting a big-bore carb, it's important to replace the restricted manifold with an unrestricted one or the venturi size is actually reduced to the diameter of the restricted manifold.
This derestricted manifold will fit any Dellorto carb up to 21 mm.
