A couple days ago I couldn't get my 47 8n going. I would get one hot spark when it first turned over, then either nothing or a much weaker spark... in any case not enough to make it run. I replaced the coil and it fired right up! This made the spark noticeably hotter on the test light, however, I'm still having issues. If I start it, run it for a minute, then shut it off and try to restart, 50% of the time it has NO spark and won't fire. The other 50% of the time it's fine. Letting it sit for a bit seems to help. I'll be staring it it with an Irish beer in hand 'til I figure it out... any help is much appreciated!
