Please help I have a 16hp briggs&straton vanguard v twin
It is only firing on one cylinder I have no spark on the one side I have changed both magneto and still no spark. I don't know what to check now.
Please help me out
Thanks Bob

Does it have 1 coil with 2 plug leads?
Either way, measure primary and secondary resistance to verify coil wire and plug cap are intact. Use the Good coil for the reference resistance.
