RK24 bogging down.

[Ohio RK24]

RK24 Boggs down and almost dies under full throttle, occurs wether doing work or just moving tractor around on flat ground.
No abnormal noise or behavior other than that, I can move around at lower throttle without problem when trying to do anything that requires higher throttle, it Boggs down, let up on the treadle and it seems ok.
I just purchased both fuel and water separator filters, some new diesel fuel, water disperser/tank cleaner plus fuel injector cleaner.

Do you buy off-road diesel or fresh diesel at a truck stop? Avoid off-road diesel as the station under ground tanks might be refilled once a year.

If you suspect bad diesel with microbes and a dark color to it, yes, change out the filters, the hose to the filter and flush the fuel tank.

Seamfoam or Gumout products work better than the typical fuel treatments out there. In fact Seafoam's original use is for diesel fuel systems.

The Yanmar engines have no issues with Seafoam. In fact, the Yanmar diesels in Deere machines for the past 45+ years are still going strong.

Yanmar makes these same engines for their Marine division. Seafoam got it's name from the Marine diesel industry as the go to source for cleaning the both the fuel and oil system.
