Points to check on a Duetto.
- Front wings/fenders. There should be inner aluminum splash guards.
- The A-pillars and door hinges.
- The sills, both inner, outer and the middle sills are
prune to rust. Lift the rubber mats and inspect.
- The doors, the lower frame should be clean, use your
fingers to feel any bubbles or rust.
- Place the Duetto on a lift and check the floors, both
under and from the interior. Lift the rubber mats.
- Rear wheel panels, especially the lower rear section
which are exposed to blasting.
- The boot lid. The rear part is vulnerable if the
ventilation holes are not covered with plugs. The rear
section is still available at most vendors.
- The carbs and the mounts. Rough idle is often due to
defective rubber mounts between carbs and intake.
- The Hardy rubber or dough-nut and the U-joints. If it
feels like a rubber hammer when taking of it is the rubber
support. If the sound is like a hammer on steep, it is
likely to be the U-joints.
- Gearbox and syncro rings. The 2nd gear is often bad. New
material in syncro rings will last a life time.
- Oil pressure should be accurate. See the information about
oil, please.
- Is the engine clean and the fluids fresh?
