I have a Sears Single Stage Electric Snowthrower: Model C950-52903-0 - 20inch. Ive had it to clean off my deck for about 6 years. It now runs poorly or not at all. I suspect the brushes are toast. I took it a part and the brush wire is not attached to the small metal things that slide into the motor slots (both sides). I've taken the brush wires into local electric service people with no luck getting replacement. Same goes for on-line searches, as these blowers are discontinued. Hate like heck to throw this blower in the garbage! Can I make some out of "brush wire" and somehow affix them back onto the metal things? Where can I get wire etc etc? Thanks!!
