I'm in the process of installing the Pertronix ignition, but before I do, I wanted to A: confirm the advance was working B: regarding McMarks thread, make sure I didn't have interference with the little advance needle While removing the points, I see a little movement (very little) of the plate. But when hooking a hose up, and sucking on it, I'm able to get any movement at all. How freely should the plate move (how much vacuum is needed to get it to move? How much movement should there be in the plate? Is there a way to lubricate the plate, without dismantling the vacuum advance? (nervous enough just having removed the distributor) (IMG:style_emoticons/default/blink.gif) Thx, Turk |

Thanks all.
I was able to clean and lube the advance plate and vacuum arm, and get the advance to move more easily. I installed everything and timed the engine and its running pretty well. The exception is its 'hunting' at idle, and I think this is a vacuum leak that I have to track down. (I have a new set of vacuum hoses on the way from AA). I'm still pretty sure that the distributor needs a rebuild, and I'll look into that. I'm gonna need to get the vacuum pump from HF and confirm the vacuum canister on the distrib is working correctly. One of the reasons I did this was I needed to get a rebuilt MPS installed (thanks Jeff B. for the rebuild) to cure the rich running I was experiencing at all times. I did that and I am really happy to have that rich running and fuel smell gone. Turk |
