Fuel mix and air screw settings

[akreider]

What are the correct settings for the fuel mixture screws and air screws for a dynojet stage 3 kit. I have pods, aftermarket exhaust and a yoshi pipe.

Adjust them individually for the highest, smoothest idle you can get. 1 1/2 to 2 turns is a good starting point but each carb may need a different setting.

What is the best way to do that? With a vaccum tool or just unplug the other 3 spark plugs? I have never done this before.

Just watch your tach and listen to how the engine sounds.

Thanks alot Billy for answering all of my random questions tonight, my mind is racing and I am trying to catch up with it.

Beats watching TV.

If your pilot circuit is clean and the screws tips are in good shape you'll hear a sweet spot when you get each one right.

You are talking about the fuel mixture screws right? What about the air jets that are located right where the filters mount? Is there a specific setting or do I just have to fiddle with them along with the fuel screws at the same time?

You should have CV carbs on the '80 and you have fixed air jets with no adjustment. The only way to get more air to the pilot circuit is to swap jets altogether which is usually not necessary. The mixture screws generally give enough adjustment range to compensate for intake and exhaust mods.
