Hi. I have an LX2610SU. Had it about year and half. The machine currently has 65 hours. The 50 hour service was performed by me. The last couple times I used it, it would start immediately and shut right down. After about 3 or 4 attempts it would run fine. I do a bunch of work and while working on and off several times with no problems. Any ideas on the hard start? The fuel level was down to 2 bars and just filled with new diesel. The fuel add didn't change anything. I did the recommended glow plug routine. This machine never saw old fuel.
