When is the last time you replaced the fuel filter?
That’s what I was thinking as well but from what I’ve read the FD611V had the tdm, the FD590V doesn’t have it. Looked on the machine and I only see the igniterIf the upper end of the fuel system is good, maybe try a time delay module? They're usually completely dead by the time I get to them. AM128906
Here’s an update, I did move to clean the carb. As I tried to remove the float pin, the float pin post broke off. Bought a cheap Chinese carb while waiting for a oem carb. Chinese carb actually works well, tractor runs fine now. Mowed the entire property with no issue so far.That is correct.
Have you done any work on the carb? As part of your troubleshooting, I'd pull the float bowl and clean it if needed.
