Einhell Combustion / Ignition Quality Problem

Frequent spark plug fouling, engine misfires and loses power

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect spark plug heat range, Over‑rich mixture, Low compression, Poor fuel quality

Safety first: Stop the engine and let it cool before removing the spark plug.

Install correct plug: Fit the exact spark plug type and gap specified by Einhell.
Address rich running: Check choke operation and air filter cleanliness as described earlier.
Use fresh fuel: Drain old fuel and refill with fresh, clean petrol from a reliable source.

If fouling continues, a compression test and deeper engine diagnosis are required.
