Hiya I have a Husqvarna 125BVX blower and am having big and expensive problems with it. It only runs (rough as guts) with the choke fully on. I have replaced the piston, bore and all the seals and also checked out all the fuel lines. The only thing that I haven't replaced is the carb. Expensive little blighter if it is not faulty. Could a faulty carb cause this symptom? Cheers Duncan
