One such item was chainsaw maintenance, and one part of that was the carburetor test. I've run chainsaws for over 30 years and never knew to how adjust the carburetor. If you have a new saw, this won't apply to you, as new regulations require saws to be built so that only a qualified technician can tune the carburetor.Here at ISE forest and garden we are one of Ireland’s most renowned professional lawn and garden equipment sales, service and hire agents.
