Hi Guys, a local landscaping service brought in a BR550 blower for a full service and check over as needed. I did the service and the blower ran pretty good. Thing I noticed was that it idles pig rich. Now here's the problem....
You can turn the Low mixture screw all the way in and the unit runs just fine. Fuel must be bypassing somewhere....and that's my question....Where could the fuel bypass? I screwed the High mixture screw all the way in and it's doing its job. The diaphragms seem OK, could do with a kit. Wondering if that may be the problem? Carb does hold pressure.
