This is the 31 Pict 3 carburettor originally fitted on Twin Port 1300cc engine, also suitable for 1300cc, 1500cc and 1600cc Single Port engines.
In our opinion this is the best small flange carburettor on the market. It has a wider throat than the 28 and 30 series carburettors, so will give a little bit more power. If you want a "fit and forget" carburettor for your single port engine then one of these rebuilt Solex carburettors really is what you want.
