Kabota KX71-3 losing power as it warms up.

[RHR]

New cylinder head, ejector bodies, and fuel filter. When completely warmed up it has no power. Any help would be appreciated.

Well your problem is quite obvious...
You must be working on a Chinese knock off unit, because we only work with Kubota's around here!


Why did you do a Cylinder head replacement?
Does it overheat?

Did you do a compression test before or after the cylinder head replacement?

Where did you get the injectors from?

Does it smoke when it does this?
And if it does what color?

Does it bog down or just low RPM?

Have you checked the air filter and housing?

New cylinder head, ejector bodies, and fuel filter.

Seems like a lot of work requiring attention to details...

Have you checked for good fuel flow from fuel tank to inj pump???????

Is fuel tank venting? I'll advise as a test to operate engine with shop towel covering fuel tank neck.
