Timing a /6, What the hell have I gotten myself into!? Options

Sorry, Noel was still logged on....and I can't delete this for some reason

Ok, how? I now understand what Ed was saying about cutting an access hole in the fire wall. What a PITA.

I would pull the vacc advance, plug it and rev to 6K. When I would adjust the dizzy it would run worse or better then worse (over the spectrum; bad-good-bad), but it would not move the timing visually. I have a couple of questions:

1. Do I need to adjust the timing to the RS cams that I had installed?
2. What is that value?
3. Anyone want to come down and do it for me?

Air "leaking" in through the #8 hole still has to go up past the plate to get into the engine, so that's not a air leak that will affect mixture. All that does is give you a idle air leak, restricting (slightly) your ability to adjust the idle speed. If you can still get the idle speed down to 800-900rpm, that hole isn't significant. If you can't, just put some tape over it to see if that helps.

If you're getting black stinky smoke, then you're probably way rich at idle. If I remember correctly, you don't have a cold-start valve anymore, right? If not, try turning the idle mixture screw a full turn (this is a huge adjustment) lean. If you can beg, borrow, or steal a wideband mixture meter, or time on a gas analyzer, I'd do so.
