Hello all, this is my first post so i better get it over as a newbie, i have a few vintage sleds, 1981 Motoski Mirrage 11, it runs like a top. my other sled is a 1979/80 (not really sure what year) motoski GPS, 503 engine, i am currently not getting spark, it has been acting up for the last few weeks, i have new plugs, replaced both coils, now not getting spark to both plugs, could this be a ground issue, as i have up plugged the harness a few times, but have checked it again, any thoughts would be great. Thx
