firing issues, Robin EH29C

[pappyjerry1989]

I have a ez go golf cart with a Robin EH29C motor. It has a white wire on the top of the oil sending unit, where does it connect or does it? I am having firing issues, Im thinking it may be like a murphy switch because it isnt hooked up, I cant find another wire it may have been connected too? Im thinking if thats not the problem, maybe its the magneto? I've replaced the igniter and coil, this all started when the starter solenoid went out, replaced it and the motor cranks as it should but somehow I lost fire, any help would be appreciated thank you..
