Step-by-Step Starting Instructions
Follow these steps to start your 1942 Harley Davidson WLA safely and effectively.
Checking Fuel Levels
Check the fuel tank for adequate fuel. Ensure the fuel is clean and fresh, as old fuel can cause starting issues. If fuel appears cloudy or has been stored for over 30 days, empty the tank. Fill it with high-quality gasoline, preferably mixed with a fuel stabilizer to improve performance.
Inspecting the Battery
Inspect the battery for charge and corrosion. Use a multimeter to measure the voltage. A fully charged 6-volt battery should read around 6.3 volts. Clean any corrosion from the terminals using a wire brush. If the battery is not charged, connect a battery charger until it’s fully charged.
Engaging the Choke
Engage the choke before attempting to start the engine. The choke enriches the fuel mixture and helps the engine start in cold conditions. Locate the choke lever, usually situated near the carburetor or on the handlebars, and pull it out to the fully engaged position.
Cranking the Engine
Crank the engine by pressing the starter button or using the kick start. If the engine does not start immediately, wait a few seconds and try again. Allow the engine to warm up for a few minutes after it starts, ensuring smooth operation. Keep an eye on the pressure gauge to avoid potential overheating.
Common Issues and Troubleshooting
Starting a 1942 Harley Davidson WLA can sometimes lead to common issues. Here’s a breakdown of solutions to typical problems you might encounter.
Engine Won’t Start
Engines that won’t start often stem from one of several common issues.
- Check Fuel Levels: Ensure you have fresh gasoline in the tank. Old fuel can lead to starting difficulties.
- Inspect Electrical Connections: Look for corroded or loose connections. Tightening or cleaning these can restore functionality.
- Examine the Battery: A weak or dead battery prevents the engine from starting. Use a multimeter to check the voltage. If it’s below 12.4 volts, charge or replace the battery.
- Verify Spark Plugs: Remove and inspect spark plugs for wear or fouling. Clean or replace them if necessary, ensuring a good spark.
- Adjust Choke: Engage the choke properly depending on the temperature before attempting to start. A fully closed choke may be needed in colder weather.
Unusual Noises
Unusual noises during starting indicate potential issues.
- Listen for Clinking: Clinking sounds may signal loose components. Inspect all bolts and fasteners, tightening any that are loose.
- Check for Grinding: Grinding noises from the starter might suggest a failing starter or misalignment. Consider checking the starter gear and its engagement.
- Notice Hissing Sounds: Hissing could indicate an air leak in the intake system. Check all connections and gaskets for wear or damage.
- Review Engine Rumbles: If the engine rumbles, it might point to improper fuel combustion. Ensure your fuel mixture is adequate, and check for debris blocking airflow.
By addressing these potential issues, you increase your chances of a successful start and reliable operation of your vintage motorcycle.
