Starts and idles ok but as bogs down and dies as soon as you give it some boot. There are posts previously about this but I'm not finding an answer besides cleaning and changing fuel filter. I've had the carb in bits and blew threw and cleaned with carb cleaner,this morning I tried a new fuel filter and tubing,still the same with fresh fuel. It's had the max of about 10 hours use now ! Spares seem to be like hens teeth,what alternative carb will go on this do you reckon? It's all I could afford at the time,please don't recommend Stihl this or Ryobi that .
