I have a komatsu FG25T-14, SN 587119A. Last week lift became hard to get started, when lift would start it would sputter and stall if you got on it and just pressed pedal down all the way. If you eased it down it would rev up smooth but not to full RPM. Took the screen off of it yesterday and cleaned it (last chance screen). Read on here about using pedal to reset the lift, so I tried that. Now lift will not start at all, not sure fuel is getting passed injector assembly. This is a dual fuel lift that is running LP. Any suggestions would be greatly appreciated.
