1. Ignition Timing
* Make sure the timing is correct. A mistimed engine won't start properly.
* Check the timing marks on the flywheel and the engine case. They should align when the piston is at top dead center (TDC) on the compression stroke.
* Adjust the timing if necessary. Consult your Ezgo manual for specific instructions.
2. Fuel Delivery and Air Intake
* Check the fuel line for kinks or blockages. Even if the fuel pump is clear, there could be an obstruction further down the line.
* Inspect the air filter. A dirty or clogged air filter can restrict airflow and prevent the engine from getting the air it needs to run.
* Make sure the air intake is clear. Check for debris or blockages that could hinder airflow.
3. Other Potential Issues
* Inspect the spark plug. It may be firing but not producing a strong enough spark. Replace it if it's worn or damaged.
* Check the fuel lines for leaks. A leak can cause a loss of fuel pressure.
* Inspect the fuel tank vent. A blocked vent can create a vacuum in the tank, preventing fuel from flowing to the carburetor.
* Ensure the choke is in the proper position. If you're using a choke, make sure it's engaged when you're trying to start the engine.
4. Troubleshooting
* Perform a compression test. While you've already checked compression, ensure the readings are still accurate.
* Use a timing light to check the timing. This will help you confirm the ignition timing is set correctly.
* Try starting fluid. A small amount of starting fluid can help diagnose if the engine is getting a fuel/air mixture. However, be careful using this as it can damage the engine if used excessively.
5. Seek Professional Help
* Consult your Ezgo manual. It should have troubleshooting sections and more detailed information on engine components and settings.
* Contact an Ezgo dealer or a qualified mechanic. They can provide expert assistance and identify any issues you may be missing.
Remember: Safety is paramount. If you are not comfortable working on your golf cart, it's best to have it serviced by a professional.
