Hello everyone, I'm new to this forum having recently acquired an old JD 755. It was running fine and I had just finished harrowing a small 1/2 acre paddock when it suddenly cut out and won't start up again. When I turn the key it fires up and then immediately cuts out. My first thought is it must be a fuel issue. If there was air in the system would the engine even fire up at all or would it just crank? This engine definitely fires up but then dies right away as if it is starved of fuel. Any advice on how to troubleshoot this problem would be appreciated.
