Hello,
Very hard to find information about alternative spark plugs to the Champion RDZ19H. Hardly any information via Google. I contacted the manufacturer of my edge trimmer (MTD 990), they replied with details and I post here just in case this can help you spare your time.

No warranty from my part for any damage to motor, I just pass the information as I received. Hope to have helped.
