Okay, I have read and re-read the replies to my 305V6 idle problems, and I have discovered a new problem. The distributor cap on my truck has a sliding window that would allow me to adjust the points without having to take the cap off. I had the window taped open so I could watch the breaker plate as it advanced the the ignition. I found something disturbing. With the vaccum advance hooked up, and the truck at idle, the vaccum advance is all the way open, instead of being at rest at idle. When I unhooked it at idle, the engine ran smooth. When I hooked the vaccum back up, it advanced the timing. I took the distributor apart, and besides this problem, a grounding wire had broken loose and I fixed that. I put the distributor back together after finding NOTHING, started it up, and the advance was fine. It was at rest at idle with the vaccum hooked up. I revved it up a bit, and it advanced like it should. But, after a few minutes, it started acting up again. It wasnt advancing it all the way, just a little bit.
What the crud is going on with this stupid thing? I have it at idle, but its drawing too much vaccum?! I have it hooked up at the back of the carb and not the intake manifold. what should I do? is it a bad vacumm advance mechanism? :mad: :mad: :mad:
