Common Mechanical Problems & Known Weak Points
Engine & Power Delivery
One common issue is the engine stalling during operation. Symptoms include sudden loss of power and difficulty restarting. This can occur due to a clogged fuel filter or faulty ignition components. Regularly replacing the fuel filter and checking the ignition system can help prevent this.
