P.Body I think that was a possibility. Because once I drilled them out just a tad bigger,
my idle screws started to finally have a bearing on A/F. Once I get another chance I’m going to lean it out just a little more and then set the idle a little higher and see if the problem is soloved. Hopefully that gets rid of the off idle stumble. I’ll keep the post informed of my finding. It could be a few days before I get back to it.
