You need to get your timing set up, at least the initial and vacumn side before playing with A/F to get a good idle.

The size of the primary jets has ZERO to do with idle quality.

Using a vacumn gauge to set your timing is not a good method. Think of how each of the three timing systems work and the purpose of each and you will see why.

Old gas can cause an eye stinging exhaust because so much fuel passes through only partially burned.

Before drilling the primary plates you need to know where they are in relationship to the transition slot. Usually adjusting the seconday plates is a better way than first drilling the primaries.

The mortec site that was mentioned is a great site and has some real good links also. Good luck. Mel
