I have a set of Solex 40 P11-4 carbs I'm cleaning for an early 912, and noticed a part missing. The part appears to be some sort of jet vent tube that is in the air flow of the throat of the carb. The part looks as if it's simply pressed into the carb top. I looked into the head/cylinders on the one side with a boroscope, and didn't find the part, or any evidence that it went into the engine. Anyone know the technical name of the part, and where I might be able to find one? Thanks!
