Hello, I have a Case 580M Series 2 backhoe that appears to be leaking fuel from the area of the throttle assembly on the engine. I am not very familiar with the machine and really don't have a lot of details to provide, except that it leaks one drop every 5 seconds at idle and more when rpm's increase. I have a few pictures here, and you can see the oily sheen on the throttle assy (best picture of the throttle is the close up third to the right). If anyone has pointers on what is going on I would very much appreciate it. Thank you.
