Is your vacuum advance working (adding 15* at idle) and is it connected to a full manifold vacuum source, or to the stock "ported" vacuum source?

Yes and Yes.  I have it set up like yours, but I really need a dial back light to see how everything is working.  I also bought two new power valves and will see if that helps.

Acts lean at idle, cruising or WOT?

All the above.

It has whatever was recommended on this site.  72/76 jets I believe and 65/85 power valves?  I just had it apart a few weeks ago as the bowls were leaking and the accel pump housing leaked because of a stripped screw.  I fixed the accel pump and used new gaskets on the blocks and bowls.  The kit I had, had two 65 power valves in it so I only replaced the front one.  I checked the back one and it seemed to be working.  However, with this timing thing I've had a few backfires.

I have confirmed that the line on balancer at 0 on timing tab is tdc.  I think there are two things going on.  The distributor lost the bushing on the mechanical advance and had way too weak springs and that combo gave way too much advance way too early.  I fixed that and got the initial to 10, but I had to really bring up the idle.  Now I feel its something in the carb.  Almost acts lean.  Some research makes it sound like the power valve.

I pulled the bolt off the balancer and felt the keyway and it lined up with the timing line on the balancer.

I have a basic timing light and when I check the timing the line is above the top mark on the tab by about 2 inches so I can't even see it.  If I bring the timing back it wont idle and stalls.  So I'm still wondering if the carb could be plugged, but why would it idle fine when I'm way advanced?

#1 is at about 7 o'clock if your looking at it from the front of the car, top down.  Rotor is past #1 at tdc .

I checked the balancer.  It's right on.  The firing order has been checked by 3 different people and is correct.  The engine runs, but at 75* advanced. I cant get the car to even run if I get the line anywhere near the timing tab.  Can't figure out how it runs at all this advanced.

So Mark, would the car run if I had it 180 out?

I had pro steering in Portland do mine and it turned out great and was reasonable.

Recently got my engine back in and running.  The weird thing was when I had the total set to 36, the car wouldn't idle so I thought the carb might be messed up.  I set the timing by ear and drove to an old performance mechanic who checked the timing and reset the carb.  I was at 76 degrees total timing.  Neither one of us could believe it would run.  But every time I tried to bring the timing down the car would die.  So I thought I had too much advance in the mechanical and put in one stiffer spring and limited the travel in the slot.  Car ran great and idled great, but when I checked the timing, the mark was 180 degrees off the 0 mark on the timing tab.  So I took out the distributor and reversed it thinking I found the answer and some how it ran 180 out.  Not so.  I had to turn it around again.

So:  The question is:  What is the best explanation for this?  Is the cam timing off enough to do this or is my carb just plugged up and I need to idle it up at 36 total?  My idle is set at 1 1/2 turns off fully closed.  Is this in the ballpark for most?  68 302 with all stock stuff except the cam.

Dimples as I recall.

I have that ball and the whole linkage and can't get $175 for the whole thing.

Hey, I'm looking for the bolt that holds the choke to the manifold.  Lost mine somewhere in the teardown.  Do you know what size and thread, headmark etc?  The AIM just says production bolt.  Thanks.
12  Camaro Research Group Discussion / Originality / Re: Wire stand on: July 25, 2014, 10:52:10 AM
Looks like an AIM error.  Thanks.
13  Camaro Research Group Discussion / Originality / Re: Wire stand on: July 21, 2014, 11:32:23 AM
I guess I'll have to assume another AIM error?
14  Camaro Research Group Discussion / Originality / Re: Wire stand on: July 16, 2014, 12:39:00 PM
Again

Baxter is the onlu place I've ever found parts like that unless you look on-line.  I'm not sure if they have them, but I bet they could get them.  There's one in Jantzen Beach
