Engine died during break-in

I have a tach wire that goes to the neg side of the coil. Someone else had said something similar so I disconnected the tach wire to the coil but it made no difference. Thanks for responding.
My tach wire is connected to the negative side as well I don’t know why I was thinking (+) Positive side.. lol..Opps.. Well Sorry it didn’t work, it was worth a shot.
