Still no resolution. We checked the valves and they stayed put after the first 2 hours on the engine...so that's good. We replaced the plug wires and plugs. We re-timed it. I am going crazy...
Has anyone had a problem of their dizzy being too retarded? Speed comes way up when the hose is removed on the retard... How many degrees at closed throttle should the retard retard the timing? Chris |

BTW, I will be home early tonight as Janet has a Music For Minors Board Meeting. My dad can be there any time today and I will be home by around 5:30. I would greatly appreciate your help. Hopefully by then, you will remember what fixed your last problem...
Chris p.s. I left a message on your cell with this same info... |

I know what the issue is. Put the throttle body gasket on correctly. You said something in one of your posts that didnt sound correct. Like you blocked the idle air passage (and I have no idea why you would have done this). With the new P+C's and everything done nicely. It needs air to idle.

The gasket seems to be "made" to cover the hole. Is it not supposed to? I don't have pictures of it, but there is the line that is drilleddiagonally from teh bottom of the TB to just above the butterfly. Our thought was, since the gasket seems to cover it, that this was part of the milling process and was supposed to be covered.
What do other's do with this? Do you know what I am talking about? I am not sure it really adds more air since that is controlled by the screw anyway (it can just get air from the bottom as well). Thanks for your help... Help, Chris p.s. So, Brad are you going to be around? You can look to see what I am talking about. We are having Lasagna tonight if you want some.... |

The vacuum retard should retard the timing about 5 degrees.
I think Brad has nailed the problem, try it. Geoff |

OK, so here is the odd thing....THE PROBLEM IS SOLVED. Brad was there while we swapped the gasket for the throttle body around. This gave us more idle speed, but it still was not adjusting properly. We put the gasket back the original way and voila, IT WORKS!
Strange gremlins in there! Also, we seem to have found the source of our sheared ring lands. Covered in another thread... Chris |

Chris,
I had the exact same symtoms on my 76 2.0. I gave up, brought it to a 2nd mechanic and they found that the intake bolts to the head were loose and or missing causing an uncontrolled vacum leak. Sounds like a good place to look since you just put your engine together. Good luck, George |
