Thanks again for the reply Greg,
That is exactly how I do check and adjust the idle mixture screws (tach and vac gauge). By unported do you mean Manifold vac for the vac adv? That is where I have it now and she runs much better than when I had it hooked up to the "ported' vac port on the carb. The canister is restricted to only pull an extra 10* as well.
For the $179 it will cost me for the MSD Digital 6A box with all the parts to adapt it to my HEI, Is it a worth while addition to my ignition? Even if I have other issues and this doesnt fix my emissions for testing (I plan to deal with those issues as well), is it worth it to add the box?
I have the top end apart right now and thought why not add it now while the distributor is out.....
I apreciate all the advice as I am a backyard hotrodder jsut trying to learn as I go with no buddies that are into all this stuff.
