I seen a different fuel problem yesterday , 323 bobcat hoe with 450 hours , wouldn't run , fuel squirtig out #1 injector only , none from 2 or 3 , pulled the injector pump and 4 screws had fallen out the plate over the sliding throttle rod , found 3 or the 4 with a magnet in the bottom of the injection cam housing , drained the oil , attached a magnet to a piece of mig wire and put it thru the oil drain fitting and fished the 4th out , put it all back together with locktite and it works , wonder it this is going to become a trend
