First off, I am a newbe, so If I am in the wrong area, sorry. I have a 197? Sears Craftsman riding lawn mower or garden Tractor. I was told it was a 76 model, but I don't know. It was stored for 20 years so it is in very good shape, though the dash is broke. The model number is 917.25170 and the ser. number is 1327 B05290. It has a Craftsman cast iron extra long engine life with solid state ignition, the number off the engine cover is 143 670032 ser 7080E. So my first question is what do I really have. My second question, is where can I find a manual or book on this. I am have some problems getting it to run. If I pour gas in the carb, she will fire up and die, if I remove the fuel line at the carb and blow thru it I can hear the gas bubbling in the tank. I want to get this old girl running again and use her around my small farm. Thanks for listening and for helping.
