OK, I need help with the massive intelligence base here. I bought anothe snow blower, came off a GT model with the tachmatic setup on it, so I think it should work on my 85 312-8. Once again there is no model number tag on the blower. Can anyone tell what model this might be? I would also like to find out where I can get idler pulleys and a chute control cable for it. Thank you in advance
