I finally got my 914 on the road but switched to carbs to save money. The car runs rich. I have heard that the stock cam is not the perfect profile for carbs and also that the car needs to be run slightly rich to keep the engine temperature down. I have never adjusted a carb before and was wondering if I should try to lean the mixture myself or if this is better left to an expert. I recall that if an engine runs lean bad things can happen to pistons and valves.

In all likelihood, you had a vacuum leak someplace in the Ljet system resulting in the low idle. There are number of spots to suspect. You need to be running a self regulated rotary fuel pump with no more than 3.5# of fuel pressure for the carbs. If you are using a noise making facet style, or FI pump with a cheap FP regulator, you need to ditch that delivery system. Hold on to the FI parts.
