Hello all- My Allis Chalmers 180 diesel starts and runs fine until it begins to surge 1-200 RPM at all throttle positions. It runs rough while this happens then the surging usually quits,
only to return again after several minutes. Injector pump was rebuilt 300 hours ago. Filters and fuel OK, but the front injector does have some fuel seepage around it ( not much ). This
injector has been leaking for many years. Thought the engine might be sucking air so I checked the fuel line fittings for tightness - all OK. I'll try some Lucas fuel cleaner or Seafoam
today, but does anyone have any suggestions? Thanks!
