BX23 Engine sputtering

[ultrarunner]

I had the same problem and the cause was a torn fuel line from a branch... once I got off the tractor, I could see the diesel leaking... had enough flow to idle but not much more.

Another thing as a long shot... one owner said his would cut out going down hill... turned out he would raise up out of the seat just enough for the safety switch to kill the motor...

Hi OR:

I thought it might be the seat at first but when it doesn't start at all but cranks it couldn't be a seat interlock.

I opened the line from filter 2 to the injector pump and the injector pump kept draining fuel. So much I wondered where it was coming from.

Turning on the fuel pump provided a steady stream of fuel from the hose.

Connecting the hose to the injector pump and pumping didn't allow me to start the engine.
Letting it sit lets me start the engine.

Eventually I drained the tank and replaced the filters.

It worked really really great after this.

It eventually warmed up, started missing a bit and sometimes made black smoke.

I know one clamp is in poor shape, I'll get some new clamps.

What do I do with the diesel I drained ?
