JD 755 Loss of Power

[fishmen222]

1992 JD 755 hydro with 820 hours. Ran great for the first five years. Ran as usual for my first cutting. Halfway through my second, I started to lose power. Ran another 30 minutes and then parked it. Replaced air filters, fuel filter, hydro fluid is basically new, fuel new. Brakes are not binding. Starts right up, but runs very rough. Do I need to pull the tank next, or does this ring a bell with someone as something familiar? Thanks folks

I'm assuming you bled the fuel system after you changed the fuel system and since you changed the air filters, the air induction system is not blocked.Check for fuel delivery from the tank. It's not uncommon to have debris clogging the tank outlet strainer and/or the fuel line.

Yes, system was bled. I will start pulling the tank tomorrow. Do I need to re-bleed the system afterwards? Do I also need to inspect the pump for debris? Sight glass filled fast after filter replacement.
