I bought an antique blower on ebay and of course it was supposed to work like new. When it arrived i found that although it worked there was quite a bit of resistance and when i really cranked it the fan seemed to make a sound like it was rubbing on the shell. Can anyone tell me how I should approach this. I would like to repair and use this blower. All help is much appreciated. I am a rookie so talk to me like i am ignorant as I am.
