I have a Craftsman ride on mower 917275180, with a Kohler engine. I can't get gas to pass the carburetor. I tried blowing, cleaning, new gas, etc. It works for a few seconds, if we spray gas into the carburetor.
These mowers use gravity feed to the carb. You may have a kink in the line or a plugged gas line coming from the tank. Try disconnecting the gas line to the carb and see if you have gas running out of the gas line.
