Hi, am having carby problems with my concrete saw. It has a walbro carby, it has HDA 189B stamped on the side. Problem is unable to get fuel primed through the carby, have put primer hose into fuel tank hose and get fuel so i know its not the primer. Have put a new kit through carby as well as a thorough clean ( was needed ) but when fuel line and primer line are both hooked up to carby the fuel wont come through, seems to be sucking air from somewhere but cant figure out where. Any help appreciated Paul.
