Re/ the pull-off, on my car I found it important to bend the link so that, when the pull-off is fully pushed in, the air valve can only open a hair, maybe .010-.020". There is an enrichment circuit that is exposed to airflow as the front edge of the air valve begins to open which could cause excess richness if it is exposed at idle or when you're up on the converter. I cured a problem on my car by bending that link so that the air valve could not begin opening until the pull-off began to relax as vacuum dropped. My understanding is that this hole acts as a secondary accelerator circuit, drawing fuel into the secondary side to transition until the main circuit is providing sufficient fuel. One of the carb guys could explain this much better, but it is another Qjet thing to check.....
