Ended up with a holley 2bbl, 500cfm. Do I need all these D@$#! vacuum lines? The original had about 6 or 7 lines coming off it. The new carb has 3. One for the pcv valve, one for electric choke, and one more spot I can't figure out. Can I tie or tee these lines into each other? Which ones do I use and plug off the others? The truck fires right up, runs for about two minutes, then dies. I figure definitely a vacuum line or too many tied into each other. Any help is greatly appreciated. |
