Hi, I have a simplicity 1960 sno-away 6hp 26" snow thrower, which worked like a charm until recently I hit the curb with the rotor and one of the blade is out of shape now ( the welded parts came off and doesn't rotate). I am wondering if anyone can refer me to a parts store etc who sells part for old blowers or if it is recommended that I get it welded back and see if it will work? Please advice.. and if possible email me at kalkama AT gmail DOT com
