I've got an old Ford 2712e 4 cylinder diesel engine on an irrigation pump. I purchased it from a clearance dealer not going (radiator was holed, no fuel tank etc.) but was told it should go.
I've managed to get it going but it wont hold a steady rpm. It surges continually. Revs climb - then drop - then climb, over and over again. It has a 'minimec' injection pump. So far I have:
- Removed the injection pump side cover and verified that the metering rack moves freely.
- Drained and refilled the injection pump oil.
- Checked for any fuel restrictions to the pump.
- I can dampen the surging by moving the fuel shut off lever over to a point where it restricts the rack movement and it will hold a steady rpm but this is not a solution.
I'm starting to think its an issue with the actual governor operation but that's about where my knowledge ends, I am not sure what to try next?
Anyone with some knowledge of these pumps have an idea what it might be?
