MSD Disappointment ??

I've been over my connections and terminals at least three times. The cars waiting for spring at this point. I am going to run a separate ground wire from batt. to engine block and change the starter then investigate other possibilities like maybe something hung up in dizzy. If I get this figured out then I will increase my initial timing and add a limit screw to dial in my full advance. I would like to get my vac. can re connected for better highway mileage if able but may not be able to without spark knock.
