Distributor

Indispensable replacement parts, the original distributor assembly was disassembled and serviced well to keep it in VW Beetle as a emergency compensating parts.
The contact point surfaces were flattened with diamond fine grain flat file.

The moving parts for ignition timing advance were adhered and partially destroyed, vanish and sticky material inside were cleaned in a organic solvent tray and after drying moving parts were lubricated in combination with Microflon, micro grain Teflon powder, for good performance in the point arm hinge micro movement portion.

Centrifugal mechanical ignition timing advancing system and replaced vacuum solenoid control valve both attained smooth movement after maintenance.
The mechanical system requires periodical maintenance to re-gain ultimate performance.

Here we find a fundamental difference in Air-cooled VW Beetle from nowadays automobile.
This is why I chose Beetle as a partner of automobile life from now.
