OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Trimmers and Brushcutters Ryobi Trimmers & Brushcutters Fuel comming back out the carb

Hi newbie here. I have recently fixed up 2 ryobi Lawn Hornets mkIII. They go really well now but tend to leak fuel from the back of the carby when sitting. Do they need carby kits? If so are they easy to install? Where can you get the kits? Thanks Anthony.
