Dominic worked with me on the build of my carbs. Although, I haven't changed anything but 1 jet size from his baseline values. I really don't expect MUCH more than what it's given already! That is based on both performance and O2 sensor feedback so, I have to call that a 'nailed-it'. I will add the metering is on the safe side which again in my book is 'nailed-it'. But for some reason we don't talk much anymore. Like anywhere else, I believe many pic his brain and don't reciprocate/compensate.
