I would.  But if the system is not working, it won’t spray.

TTS sense air temp below the plenum to have the cold start valve function on start-up for more fuel when the engine ic cold...I've seen many more cold start valves fail than the TTS...I would pull the csv and check the spray and pattern into a clear jar first...

  Hi to all,

  It is an old air-cooled engine.  Has starting trouble cold.  
  I am to test the Thermo time switch.  I can’t find instruction in the “Bible”, only to test the wire that leads to it.  
  That test says; your test light will light up when you turn on the starter.  Fine.
  I only checked continuity there and it has.  

  Now, I just don’t know what it the best way to check the switch while it’s in the car.  As You all know, it is under the air distribution box and other wires and the fuel lines are all in the way.  Only with a long pair of pliers can I get the plug on or off.  
  I imagine, the switch is to make contact and no-contact to close a circuit.  

  Question; what should the position be while it’s cold.  Continuity or not.  

  Best wishes to all,
