HOT EDWARDS 2 Cylinder Low Tension Magneto. Bench tested – HOT with test light and I recharged the magnets. 3″ x 2 3/4″ with. 2 mounting holes that are 2 apart on center.

Please feel free to call me with questions. My parts inventory has grown out of control, so set a reminder to check back frequently for new listings! If you don’t see a part you need listed, good chance I just haven’t gotten around to it yet, so just check with me. Like I said, I have been doing this a long time and try to list everything accurately and to provide a detailed explanation of the item, both good and the bad. If you decide you don’t want it or find another one cheaper, I won’t take it back. For example, if my measurements are wrong I would take it back. Most of my parts are listed “AS IS” and are in unknown working condition, unless otherwise stated. Be sure to add me to your favorites list.
