Is the cable connection tight to electrode? Sand off the electrode with light sandpaper and clean the ground and tighten.
If there is any high resistance from dirt or connections, you loose the voltage to arc at electrode drastically.
Must be tight, clean and full voltage from high voltage circuit.
Thank you Craig,
Igniter works well, pilot light does not light every time. Sometimes requiring 3 goes.Pilot tube has been cleaned and is free of obstruction. Any further advice?
