How much is the timing mark "walking"? more than a 3/8ths" and I would check the dizzy shaft for excess play...

However, shouldn't the dizzy have a spring under it? If so, then its missing, and I'm not sure how that will effect things. How do I identify excess play? Up and down, side to side, or both? |

There is some up/down play but there shouldn't be much at all of side to side play of the shaft. A wobbly shaft gives you crappy timing and injection timing.

I felt it back when the motor was out of the car and I thought it was OK. But, its not like I'm any distributor expert. I'm going to pull it tonight and put that new vacuum canister on it so, I will double check it then. THX for all the advice BTW (IMG:style_emoticons/default/smile.gif) |

The Pertronix should have cured *minor* distibutor shaft wobble. So unless it's really bad...

OK so, I installed the new vacuum pod and un-deleted my retard. It definitely made a difference in the behavior of the idle. I re-timed the car and ran it around a bit. The idle was still hunting, so I stopped and made some adjustments. Now it idles pretty steady. It oscillates a few times and stabilizes. I have the knob fully rich, which bugs me a bit. Hopefully I can get it on the CO analyzer Saturday.
I also checked the dizzy shaft and its tight. And, I checked my charging system and had a minor scare. I put my battery on a trickle charger before work to top it off, because its been sitting for almost a year. I used my DMM in the morning and it worked fine, but I forgot to shut it off. Charged the battery, home for lunch, test the battery in my running car at lunch. DMM is telling me 9Volts. I'm shitting but, eventually I suspect my meter. Test the car with another meter and it reads as expected. My DMM went south between breakfast and lunch! |
