<VV> Two Questions

[Smitty Smith]

Smitty Says:  Question # One.  Why does Spike continue to stagger on, running after the key is off?  Alternator conversion and standard ignition.  It is not "engine run on" in the normal "poor fuel" fuel sense.  It dies as soon as the battery disconnect is pulled.
  Question # Two.  It has been recommended to use a solenoid controlled by a switch on the throttle linkage  when using a Vac Adv/ Press Retard unit with a turbo.  What are we trying to accomplish ?
