I got through the carb and it definitely is improved. The slow jet was plugged and the small emulsion tube was blocked. At first I set the mix screw at 1 1/4 and it ran poorly. I opened it to 1 1/2 and it was better. If I get bored I may pull it back off and open it some more. Still has an occasional miss at idle but it is running good enough to be rideable again. All in all she is running much better.
