Engineer never mowed a lawn before!
Less than 2 years old - probably has 15 - 20 hours of use on it and the coil fails. How does that happen. My neighbor - bought exact model off my recommendation - he has less hours than mine - same exact failure! How does that happen?! There are no moving parts in a coil!!! Found more of same online!!! The first question I would have asked the engineer/designer of this thing is: Have you ever mowed a lawn before? The way the spark plug is seated, and the whole handle extension arm piece was/is totally idiotic. Because in manufacturing the whole likely made before the bend which allows for warping/twisting - in my case twisting - taking almost an hour to get aligned correctly along with trying to keep the non-secured nut from falling out while pushing a screw through the mount holes while using my third hand to 'twist' to allow all to line up!!! That should have been my queue to take it right back and putting the words "Yard Machine" on the list of words - never to be used together again when talking about lawns, mowing or otherwise! I hope I can or have saved you some money on this one - be afraid, be very afraid of Yard Machine.
