I have a Yamaha Pro 50 LF that runs rough ,
Checking for spark at the plug wires shows that there is spark there but not very stong .
Pulling off a plug wire on #1 cyl shows no difference in its running , 2&3 show some difference .
When I moved the coils around with #1 to #3 , number 3 was dead .
When I pull all three of the plug wires off individually I can hear a snapping on all of the wires but very weak even the coil that does not fire the plug, etc. #1 coil that I moved to #3 .
Do you think that this is a coil problem or is it deeper in the electrical system ?
Thanks for any help
