Cold Condensation on Intake Manifolds (weber IDFs) Options

[tornik550]

I recently replaced my intake manifolds on my 914. I had a crack in my old manifolds from over-torquing them, Now I noticed that I have a lot of cold condensation on my new intake manifolds after running the engine (I didn't notice this with the old carbs but I dont remember ever checking). It occurs on all cylinders. I have a 2.27l with dual weber idfs. It is idling a little rough but I am working on some jetting issues so I am not sure what is causing that (I assume the jetting issues). I removed one of the carbs about 5 minutes after running th engine and there was a large amount of "fog" in both manifolds. I couldn't smell it from my position so I couldn't tell if it was gas vapor or water vapor. The intake manifolds are very cold. My engine is sucking in a large amount of air. With my "snail" synchronizer, the readings are always towards the top (25) at idle).

Is this normal? Any ideas?

Also, when I changed my intake manifolds, I also changed to 34mm venturis from 32. This is why I am changing my jetting. I assume that the vent increase is the cause of the increased air. Not sure if that is the cause of the condensation.
