This is my first experience with Husqvarna and back pack blowers,(model 130BT) so I may be unduly concened. I followed the instructions carefully and the blower functioned really well. I was surprised how smoothly the engine operated even on idle. Now after about 5 hours of use the engine idle has become quite rough. There is a good deal of vibration at low speed and on idle. Is this normal? Should I be concerned? I adjusted the idle speed but that didn't affect the roughness. I also pulled the spark plug, but it only had a small amount of carbon deposit on the rim -- not the electrode. So I'm puzzled because at high speed the blower works well and vibration is almost non-existent. Could you advise me on what to do -- ? Buntfb
I have just bought a new blower (model 130BT) and in the manual it states an optional flat nozzel but I can not find a part number or place to order>
