If you have a rough idle I suspect you are still too rich on the idle setting. A lean setting would be very smooth until it suddenly just quits. Try leaning more on the idle screw until it does indeed not idle, then start to enrichen and see how that works out. With a rich setting, you have to have a higher idle to kick out the excess fuel. A lean idle adjustment allows much lower RPM idle speed. Good luck there and be patient. As your engine breaks in and you get more used to it, all this should become easier. Always takes me a while to dial in an engine and understand it, but I am still learning after 30 years in the hobby.
