I was preparing my FX 140 for the season which required me to rebuild the jet pump and bearings after 18 years in salt water. I was running the machine on the hose in my driveway when I noticed the fuel line was leaking to the fuel injector rail.I pulled the hose and replaced it with one from AutoZone that are clamped to the fittings. Since this work, the machine will run but only with a hand on the throttle keeping the RPMs above 3000. I ran the machine in the water and it runs fine above 5000 RPM but stutters at the the lower end. I don’t see any fuel leaks or reasons to suspect my repair, but this behavior is new to a machine that has run reliably for my 12 years of ownership.
