the only vacuum line I have line I have is for my vac advanceIf you've checked all the vacuum lines, (including the brake booster). The only other thing could be the Air/fuel screw. It should not be screwed in all the way. Back it out until it levels out. Have you got a timing mark yet? Try timing it by moving the distributor. you could be too much retarded. That will fuck up the idle. They run a lot better a little advanced, about 5 or 6 degrees.
Glen and I cut our teeth on these dinosaurs. But it's a lot easier when it's sitting in front of us.
Good luck Benn. I hope you can sort it out soon.

I have the front and rear floats set, but looking through the screw on the side of the bowl, u give the truck a lil shake and fuel comes out, so its set,Hey Benn, sounds like things are starting to come along. Any of us who have had a distributor out have had them go back in a tooth or two off. Just part of the learning curve. We've all had them go in 180 degrees out also because we got in a hurry and had them at TDC on exhaust stroke instead of compression stroke. Check your fuel levels by removing the screw on the side of the fuel bowl and watch for fuel to just trickle out the hole or level with the bottom of the hole. Adjustment is with the screw and nut on top of the fuel bowl. Idle mixture screws can be adjusted using a vacuum gauge to get highest vacuum and then turn screw in about a1/8 of a turn. You will have to go back and forth from each screw to balance them out. Until you can get the proper timing pointer it's going to be tough the set the timing. Just remember it doesn't take much of a turn to advance 5 or 6 degrees. Once you have the equipment to time it remember to disconnect the vacuum hose at the distributor and plug it in order to set timing and then put it back on the vacuum advance. A golf tee works great for temp plug on a vacuum line. Are you running aftermarket spacer or the Ford one with the connection for a brake booster? If you get a minute hook up your vacuum gauge and let me know what you are running for vacuum. Have fun.
