Re: Tach reading??
Most modern tachometers will work fine with the tach output signal from the 6A. What kind of timing light are you using ? The "dial back" type lights do not play well with MSD ignitions. Also, make sure that the two wires going from the MSD to the coil are "twisted" as shown in the MSD instructions.
