The emulsion tube is a clever and important part of the flatside carburettors as it holds a charge of fuel for a quicker throttle response, and thus helps lessen the chances of seizing when throttling down after a long, open throttle run.
It screws into the carburettor body under the pilot/idle jet. This replaces the emulsion jet fitted and is a 'straight through' jet, with no numbers, but still holds the charge of fuel.
Suitable for any Lambretta or Vespa fitted with a VHSH or VHSB flat slide carb.
