One of those two ports is carb vacuum ( vacuum at high rpm)..
The other is manifold vacuum ( vacuum at idle)..
Start it up and pull off the plug. The one that sucks at idle is the one you want to hook up to the vacuum guage.

Just leave it in park to adjust the idle mixture screws, using the vacuum guage.

Then set the finish rpm in drive (with the a/c on..if you have a/c).

A 'strip kit' is a metering rod and jet kit sold at Jeg's or Summit or your speed shop. You can adjust the fuel mixture a lot more precisely.

Hope the info helps.

Thanks, but I have a couple of questions. Do I set my rpm where I want them to be while in gear or in park and do I set that by using the throttle screw? Also, there are 2 ports on the front of the carb one is higher than the other; which do I attach it to?

What's a strip kit?

P.S. I need a tech like yours
