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 |

Yep, I'll try plugging the hose, and see if that addresses the idle hunting. (That should be a sign that the can diaphragm is bad as well, huh?).
I have the valve adjust materials, and oil change stuff coming, hopefully in a few days from AA. I'll keep my eye out for a can, or even a full distrib. I found a couple of references to this place that rebuilds distributors: http://www.philbingroup.com/rebuilt/distributors.htm I may consider that as well... I still need to, after the valve adjustment, verify my timing and make sure its spot on... I'm wondering if the "27 BTDC" is still correct if the vacuum advance is not working correctly? Any other suggestions? |
