Why is my Kubota Portable Generator emitting black exhaust?
V
Victoria CampbellAug 20, 2025
If your Kubota Portable Generator is emitting black or dark gray exhaust gas, it could be due to several reasons. The generator might be overloaded, so reduce the load. Using low-grade or unsuitable fuel can also cause this issue, so switch to the specified fuel. A clogged fuel filter or air cleaner could be the culprit; replace or clean them, respectively. Finally, deficient nozzle injection can lead to this problem, requiring you to repair or replace the nozzle.

Alan LewisAug 23, 2025
If your Kubota Portable Generator's engine revolution isn't smooth, several factors could be responsible. A clogged or dirty fuel filter is a common cause, so replace it. Similarly, a clogged air cleaner can lead to this issue; clean or replace it. A fuel leak due to a loose injection pipe retaining nut can also cause this, so tighten the nut. Other potential causes include a malfunctioning injection pump or governor, incorrect nozzle injection pressure, or a stuck/clogged injection nozzle, all of which may require repair or replacement.

If your Kubota Portable Generator is overheating, several issues could be the cause. Check if the engine oil or coolant levels are insufficient and fill them as needed. A broken or improperly tensioned fan belt can also lead to overheating, so replace or adjust it. The radiator net and fins might be clogged with dust, requiring cleaning. Corrosion inside the radiator or coolant flow route, a defective radiator cap, or a damaged radiator hose can also cause overheating, necessitating cleaning or replacement. Overload running should be avoided by reducing the load. Other potential causes include a defective head gasket, incorrect injection timing (adjust it), or using unsuitable fuel (use specified fuel).

If your Kubota Portable Generator is producing white or blue exhaust gas, several factors could be the cause. Excessive engine oil is a common reason, so reduce it to the specified level. Worn or stuck piston rings and cylinders can also lead to this issue, requiring repair or replacement. Incorrect injection timing may be the culprit, so adjust it. Deficient compression can also contribute, so adjust the top clearance.

If your Kubota Portable Generator has deficient output, several issues could be responsible. Incorrect injection timing is a possible cause, so adjust it. The engine’s moving parts might be seizing, necessitating repair or replacement. Uneven fuel injection can also lead to this problem, so replace the injection pump. Other potential causes include deficient nozzle injection (repair or replace the nozzle) and compression leaks (replace the head gasket and tighten the cylinder head screw, glow plug, and nozzle holder).
