Having some difficulty with a 2~3 year old Power Smart 22" blower I looked all over the web for assistance. There is scant information concerning this brand from Amerisun. I took it apart today and found that squirrels (I think) made a large nest in the transmission - pictures attached. After cleaning the transmission I noticed the friction wheel's tire was all chewed up but I had requested price and availability of the tire from Amerisun and their customer service sent me the entire assembly - free. I hope the pictures will be of some use to other owners of this brand.
