<p>The carter adjustments are 3 turns for the air mixture screw, a 1 1/2 for the idle mixture screws.</p>
<p>The car should stall out with the fuel mixture screws turned in. That is telling me you have a vacuum leak somewhere. As Tony mentioned, are you capping the vac line to the distrib?</p>
<p>Turning the air mix screw out is going to lean out the fuel mixture. It is difficult for me to get the mixture correct, so I installed a air/fuel mixture monitor to get it spot on.</p>

<p>Ok, I just had a brainstorm thought. I did replace the original phenolic carp spacer with a reproduction unit from OPGI. The 3/8" connection on the original for the PCV connection had a very large hole for the vacuum inlet. The aftermarket spacer had a very small hole, about 1/8" ID but still accepted the 3/8" ID hose. Maybe, just maybe, I am not drawing enough air through the PCV Valve which would cause the slight overly rich mixture. Hmm, I have a plan. I will repost after I do some…</p>

Stay tuned boys and girls. Happy Easter to all!</p>
