Re: Miss at Idle

You didn't say that you had adjusted the idle mixture screws at the base of the carburetor - if you haven't done that it could very likely be the issue though I suspect there may be more to it as your manifold vacuum of 16 inches (not psi) seems especially low for an engine with such good compression, I'd expect the manifold vacuum to be more like 19 or 20 inches. So you might try temporarily blocking off all the vacuum outlets right at the source, and then try adjusting the idle mixture and re-evaluating.
