Thanks to those of you with suggestions on curing my Duetto's misfire at idle. I pulled the idle jets out of the webers (for the second time) and discovered that I may have focused my attention on the wrong area the first time. I was spraying carb cleaner in the weber body and making sure all the ports were open and clear when I think the problem was in the brass jets themselves. I carefully cleaned the bottom pin hole with a thin wire and reassembled. Misfire was gone! (at least for a while) I now have a smaller single cylinder misfire but I think I'm on the right track. I also checked the valve lash and found good gaps there, but at the same time was able to take a fair amount of cam chain tension out with the tensioner. It's possible cam timing was contributing. Made it to the awesome convention concorso, along with some other Maryland Alfa fun, so all in all, a great success in getting the old Duetto into the daylight.
