Kohler and Jacobsen Greens King Engines: When to Repower
Introduction
Maintaining greens grooming equipment can be costly, so it's often preferable to repair rather than replace. However, when your mowers or rakes start sputtering or dying mid-job, it's tempting to consider new equipment. Before making that decision, follow these diagnostic tips to determine if a new engine is needed instead of a complete replacement.
Diagnosing Engine Problems
Remember that an issue in one engine part can manifest as a symptom elsewhere. For instance, what seems like a governor problem might be a faulty carburetor. Follow these diagnostic steps to evaluate whether repairing the engine is worthwhile or if it's time to invest in a repower kit with a more efficient motor.
Problem: Engine Will Not Start
Engine start issues are often due to fuel or ignition problems.
1. Fuel Check: Ensure the fuel is fresh and the oil/gas mix is correct. Surprisingly, bad gas is a common cause of failure.
2. Spark Check: Remove a spark plug and ground it to bare metal on the motor, then spin the engine. A blue spark should jump the gap. If the spark is weak or absent, try a new spark plug. On older machines, clean and set the points. Newer machines may require an electronic ignition replacement.
If you have spark but the engine doesn't start, inspect the carburetor.
- Fuel Flow: Confirm that fresh gas is reaching the carburetor. Check that screens are clear and the fuel cap vent is open.
- Starting Fluid: Prime the carburetor with starting fluid. If it runs briefly then stops, the carburetor likely needs rebuilding. Quality carb kits are readily available from dealers.
- Air Leaks: Ensure all screws and bolts are tight and gaskets are intact.
Problem: Engine Starts But Runs Poorly
If the engine dies, surges, or only runs on choke, the carburetor might be the culprit. Often, a thorough cleaning and rebuild will solve the issue. Use the engine manual for guidance.
Other Engine Problems
If your motor shows oil leaks or smoke, it's indicating there's an issue.
- Oil Smoke or Leak Near Carburetor: This might mean cleaning the drain holes in the breather cover and replacing the gasket. Stock up at stores carrying Cushman, Kohler, or Jacobsen parts.
- Oil Smoke Through Muffler: This can signal worn rings or valve guides, suggesting the need for a new Kohler engine.
Conclusion
Multiple issues in worn-out engines might require frequent repairs. To avoid constant shop visits, consider a complete repower with a new or remanufactured Cushman engine. Prioritize this if ongoing repairs outweigh the cost and hassle of a replacement.
