[GenX Porsche]

I have been tackling my new 911 and trying to get it up to decent running condition. I currently have a starting problem in that I believe that I am running too rich. My car is hard to start...mainly the car will rev up to 2000 rpms and then die and the gas pedal has no effect. After doing this 5 - 10 times the car will start but run rough and finally level off at a good idle. When I hit the gas after that it takes a second or two for the rpms to increase and it feels like the car is bogged down. So I believe that I am having an issue with fuel mixture. Does anyone have suggestions on how to go about fixing this? I was just going to turn down the mixture and give that a try. Also I am waiting 2 weeks or so for my fuel pressure gauge so I can diagnose further. What I am looking for is suggestions on where to go now or am I stuck waiting for my gauges to be delievered?
Thanks alot.
