I have an old 1984 Encore 48" WB. Last year I took it to the shop to have a general maintenance done. I drove it off my trailer. Got a call 3 days later saying they still couldn't get my mower running and it needed a coil. I thought that was a big coincidence that it ran when I brought it, but possible. $125 later I got my mower back with a new coil and my kill switch missing. Last week (one year later) I took my mower to another shop because it died suddenly. That shop says the coil is the ORIGINAL coil. It still is working fine so they aren't trying to sell me anything. They got my mower running with asimple fix. So I went back to first mower shop and said hey, "you guys charged me for a new coil and the original is still on the mower". The manager of the shop says there is no way to tell if it is an old coil or a 1 yr old coil. He says after a year a 1yr old coil left in the weather will look just like a 23 year old coil! Help me out guys....Is that true?? Will a 1 yr old spark plug wire and coil look as bad as a 23 yr old coil or are they thieving?? Thanks for any replies.
