Why is my Kubota Engine difficult to start?
- MMatthew FieldsJul 29, 2025
If you're having trouble starting your Kubota Engine, several factors could be at play. Insufficient compression due to leaking valves or worn rings, pistons, and liners may be the cause; consider replacing these parts or grinding the valves. A dirty air cleaner, which should be cleaned every 100 hours, can also be the culprit. Ensure the fuel injection pressure is correct and that you're using No. 2-D diesel fuel to prevent injection pump wear. Also, verify that the valve clearance is properly adjusted when the engine is cold. Overheating of moving parts may also make it difficult to start the engine, in this case, check the lubricating oil system and injection timing.
