1. Starting Problems

Causes

• Power Issues: The main power switch might be off or faulty.
• Fuel Problems: The fuel pump might not work, or the fuel tank could be empty.
• Dirty Air Filter: A clogged air filter can block airflow.
• Electrical Issues: Wires might be loose, or the starter coil could be damaged.

Solutions

• Check the Power Switch: Make sure it’s on and clean the contacts if needed.
• Inspect the Fuel System: Test the fuel pump and add fuel if the tank is empty.
• Clean or Replace the Air Filter: A clean filter ensures proper airflow.
• Fix Electrical Connections: Tighten loose wires or replace damaged parts.

2. Engine Runs Only at Low Speed

Causes

• Throttle Issues: The throttle coil might not work, or the throttle could be stuck.
• Fuel Supply Problems: The fuel pump might not supply enough fuel.
• Clogged Carburetor: Dirt or debris can block the carburetor.
• Low Oil Levels: Insufficient oil can reduce engine performance.

Solutions

• Inspect the Fuel Pump: Clean or replace it if necessary.
• Clean the Carburetor: Remove dirt and adjust it for proper fuel flow.
• Add Oil: Fill the engine with the right amount of oil.

3. Cooling System Failures

Causes

• Thermostat Issues: The thermostat might be set incorrectly.
• Low Refrigerant Levels: The system might be low on refrigerant.
• Blocked Condenser: Dirt or debris can block the condenser.

Solutions

• Adjust the Thermostat: Set it to the correct temperature.
• Refill Refrigerant: Add refrigerant to the recommended level.
• Clean the Condenser: Remove any blockages for better airflow.

4. Electrical System Problems

Causes

• Faulty Wiring: Wires might be loose or damaged.
• Dead Battery: The battery might be old or not charged.
