Idle Solenoid or Idle Enrichment Device
I have a 1970 911T 2.2 with 40TIN Zenith Carbs. On the passengers side carb there is an (Idle Solenoid or Idle Enrichment Device ) with a spade fitting
for a wire. My question is where dose the wire go from there? |

It should go to a microswitch which is activated by the driver side carb. The switch gets power from the RPM transducer(or Speed switch). When you close the throttle at speed, lift off gas as you come to a light but haven't put in clutch yet for example, above about 1375 RPM power is supplied to the solenoid and gasoline is sprayed into the cylinders to prevent lean runon. That's the backfiring you get when you lift off the gas pedal at speed. Really it also helps emissions, and that is way it is there. Mine is disconnected, and when the carbs are tuned well, I don't get enough backfiring to bother with hooking it up. Besides the gurgling makes the car sound like a racecar. Hope this helps.
