Snow Blowers

i have a st330t. i have had a track drive for twenty years. it was a craftsman snow thrower. i never had a problem with it until last winter when it didn't start. i looked around and seen your thrower. i bought it and after a few snow falls i notice the triggers were hard to work. Fasco store took it back and worked on it. that was last winter and this year in sept i called Fasco and told them that they should work on the problem again. they work on the trigger cables and other things. on our first snow fall i started it up and tried to move it and it wouldn't move. i called them again. they took it and worked on it again changing the cables again and also changed the transmission. now the speed changed from a very fast walk to a very slow crawl. if you want the whole story please call me and i will explan to you what happen.
