This VW type 1 distributor is an SVDA or Singe Vacuum Dual Advance distributor. It requires a vacuum signal source from your carburetor while also using centrifugal force to change the advance curve for the timing of your ignition system.
The ignitor 1 electronic pickup in this distributor requires 12 Volt DC for operation. Hooking it up backwards, even momentarily will kill the unit. We can get the replacement units if needed.
