Something I discovered while exploring why my 660 Tour was popping and backfiring at idle and stalling at low rpm. It turns out that the Coasting Enricher was corroded with some kind of yellow crust. It is located behind a circular cover on the left side of the left (primary) carb. Remove the two screws and be careful not to damage the diaphragm or spring. Clean and back together and running great. I hope this helps someone struggling to figure out poor low rpm and idling.
