just looked at flywheel keys they are fine, the coil wire i notice has some cuts in it. and i just check for spark again and it has none its weird because the other day it had spark and it started only with stater fluid and ran for an hour-2 hours ( did front back lawn) then the next day no spark. and the magento and coil are nice and silver no rust and the gap was set with a bussiness card. could the coil be gone?
