One thing I can tell you. Mine ran obviously rich at idle until I got that circuit jetted down. Even when the idle screw told me it was at its best setting. I mean, the exhaust was enough to make you have to walk away. I'm running stock chokes 35mm??? Can't remember at the moment. My mains are at 140. My pistons aren't high compression but I have the old small chamber heads. Every build is different, I'm sure you'll find your sweet spots.
