I am having a major "too rich" issue. Holley tech told me to measure the vacuum at idle and divide that # in half to get the power valve size to go in it. So I went and bought a combination vacuum pump/checker and hooked it to the PCV vacuum hose. It only reads about 2.5" of vacuum at idle and the number goes up as i rev the motor up. Then I hooked the vac gauge to the other vacuum line that goes to the tranny. Same thing. Reads about 2.5" and the needle shakes like crazy. Needle goes up as you rev it. Am I checking this right? The motor has a .629/605 lift cam in it and supposedly has about 300 miles on it. The fuel pressure gauge near the carb runs at about 7.5 psi until it warms up - and then it goes to about 3. I really don't know if this is an accurate reading or not - on the other thread a bunch of guys said it was probably the gauge. I drove it about 40 miles last night and It never quit - so it must be ok. The car runs extremely rich - I checked the oil when I got home and it looked like it had gotten some fuel mixed in with it. Puts out a ton of fumes. Smokes when you first start it. It seems to run ok when you stand on the gas, but seems like it is cutting out a little at say 40 mph (2500 rpms) Sorry for the length of this but I need help!
