The 034 SVDA (Single Vacuum Dual Advance) is similar to the 009 but in addition to the centrifugal advance, also features a vacuum advance facility giving an extra 10-12 degrees of advance. This allows it to 'sense' the engine load, adding some advance when necessary. This eliminates the 009 flat spot and the extra advance when cruising on a light throttle saves fuel and leads to cooler running temperatures.
This is our recommended distributor for all air cooled VWs where a suitable vacuum port is present on the carburettor.
Please note: To be used with a Standard or Uprated ignition coil, with a resistance reading above 1.4 ohms. Not suitable for use with copper HT Leads
* Note that early cars with Solex 28 PICT or 30 PICT-1 do not work well with an SVDA
** With Dual twin choke carbs, the SVDA works even better if an anti pulse valve is fitted between the carb and the distributor.
