Mower is running on about half power. I suspect it has something to do with carburetor. I contacted the local parts supplier for a rebuild kit and they have six different part numbers for this mower. I have to say this mower has been a POS since day one. It has never held a charge since it was two weeks old and I have had to prime the carb since day one. The battery was replaced twice under warranty. This is not one of the Homedepot mowers.
