usually when i started my merc this weekend first time of the day it would be popping on the middle and lower cylinder and not the top. found it to be bad spark as the cylinder was dead cold. everytime i jammed the wire into the coil or wiggled it it would pick up and run on all 3 all day. put it on the trailer, next morning same thing, 2 cylinders, wiggle it or jam it and it would pick up again. my question is the wire is shot, but do i need a coil too you think? when i pulled the wire out of the coil it left the press fit connection inside and once i got that out i cleaned out the coil and have a nice shiny copper cup awaiting a new wire. the wire was junk and corroded etc. so opinions does this sound just wire or coil too? im thinking wire.....also, can i just replace the one wire as the other 2 aint broke so why fix em.
