Update on erratic idle and stumble

[86sebring]

The crappy idle and stumble continued even after I switched the edelbrock for a Holley carb, so I figure it has to be something else. Today I fiddled with the vacuum advance in the distributor, loosened it and moved it around a bit. Right away when I started it afterwards, there was great idle, no more stuttering until I drove it for a while and then it started again. Could it be that it gets stuck in full advance mode and therefore has no idle?
How hard is it to rebuild a distributor and are there rebuild kits available ?
Or should I just get a aftermarket distributor?
thanks for the help

Yeah, I have the full msd setup and its night and day over a stocker. Save yourself some headache if you have the money and get the box/coil/dissy all together. You can sometimes catch a deal on ebay on used boxes. I have had bad luck with coils off ebay though getting bad ones

I ran a mallory Unilite for years on a daily driver with no issues. I think the MSD ones are better but they cost twice as much and I don't think they are twice as good. Of course the Mallory costs three times as much as a factory refurb and I don't think it is three...well you get the picture

Do you have any friends or know anyone in the club that will let you swap theirs into your car for an afternoon to conclusively determine if that was the problem?

I would recommend trouble shooting the problem rather than just removing and replacing parts. However, I'm not the one to give advice on troubleshooting. I don't have much experience with working on older carbed vehicles.

My I6 has never had any problems, so I've never fiddled with it. Hopefully someone will post some troubleshooting advice.
