Has anyone had any experience with the MSD y block dizzys? I'm getting weak and sporadic fire at the plugs. My car sounds like it's only hitting on four cylinders. It's puzzling as last weekend we had it running and it sounded good but had to have a battery charger hooked up. As soon as it was removed it would start misfiring again. I thought I had a flooding problem because it smelled very rich but I now think it just wasn't burning all the fuel. When I put everything together I put all the wires to coil exactly back the way it was with the 6 cyl. Should I have ran a new wire to coil to produce a full 12 volts? If so where on the car can this wire run from?
