I have a FM jb4 magneto I'm trying to figure out, cant get a spark out of it, I have read all I can find on the topic and need to know how to troubleshoot it.
for one I cannot see a "beveled" tooth on the drive gear to line up the top gear, I think I see a dot on one tooth, is that it?
how much resistance should I measure when ohming out the coil?
or am I all wrong, looking at what I'm looking at, and where should I start to trouble shoot it ...Thanks!
