Kubota T1870 engine cutting out

[Philip Lee]

My 2004 T1870 is having a stalling issue. The engine is occasionally cutting out and stalling. It happens quite predictably as follows:
- starts to happen after the engine warms up (maybe 10-15 minutes
- when I go over the edge of a hill and point nose down (it is fine nose up a hill)
- when I turn abruptly to the left although occasionally also to the right

At first, I thought it was the seat safety switch however that is not it. I discovered that as it is stalling, you can 'recover' it by pulling the choke momentarily. If it were electrical switch, the choke would not affect it.

- It appears to me that it is a fuel issue, not electrical (safety switches).
- I checked the fuel lines back to the tank and they appear to be secured as expected.

1) I am thinking to replace the filter (cheap & easy)
2) What after that? Is there something in the fuel pump or carb that would be affected by incline?

Feedback is most appreciated!

the float in the carb would be most affected by incline, assuming the fuel tank has enough fuel in it to be picked up..

agree. have a zero turn walk behind mower that will occasionally do just that, but quickly regains when the angle is changed. float related
hope you're using ethanol free fuel, & yes, wouldn't hurt to change inline fuel filter

possibly the fuel level in the float bowl is low due to a restriction somewhere. if the engine uses more fuel than can be delivered to the float bowl, the level will go low, and be critical of angles.. check that the needle valve don't stick, and the float don't have holes, also!..
